Two things are certain about the 2012 Cardinals:

They will stage a riveting quarterback competition in Flagstaff. And when they leave training camp, they’ll have one of the best backups in the business.

Assuming Kevin Kolb is still working in Arizona.

“You’re never certain of anything in this world,” he said before leaving for West Texas. “But I am very confident they’re going to keep me around.”

As the offseason begins in Arizona, Kolb is finally feeling normal. He hasn’t played since the first series against the 49ers on Dec. 11, when he took a knee to the back of the helmet. He watched Sunday’s game in sweat clothes, wearing earplugs to protect his brain.

But this time, he was fully engaged in the Cardinals’ 23-20 victory over Seattle on Sunday, exhorting his teammates along the way.

“The last five days I’ve had no symptoms,” Kolb said. “I felt really good on Sunday, and that’s the first time that I’ve felt right on game day. I don’t know if you saw me, but I was a lot more emotional. I was into the game. It felt good to be that way again.”

By now, most people understand that concussions can be menacing. A leading doctor in the field said he knows of a NHL player who began the season on the inactive list and has “contemplated suicide numerous times” because of severe depression and memory loss. The injury should never be minimized.

Yet Kolb’s first season in Arizona was underwhelming. He missed games due to turf toe, fretting that the unmanly nature of the injury would make people think he was “a big weenie.” He missed the last three games with a concussion. He won only twice in nine starts.

It was not the impression he wanted to leave in his first year, after publicly declaring his love for Valley living.

Meanwhile, Cardinals fans are becoming emotionally vested in John Skelton. His bad throws are maddening. His victories are always gritty and rarely pretty. But he fights and he wins, and on Sunday, after fainting in pregame preparations, he left the field with an oozing sense of conquest. He was pumping his fist and acknowledging the fans. It was like he owned the place.

After winning 6 of 8 games, Skelton’s voice has grown, too. He speaks like a starting quarterback, not a designated driver dangling a set of keys. He has newfound credibility with the guys in the locker room, and there is no longer a clear hierarchy at quarterback in Arizona.

“That’s what this is all about,” Kolb said. “Everyone fights for their jobs everyday in this business: coaches, players, trainers. There is always someone nipping at your heels. John (Skelton) is a competitor. Rich (Bartel) wants to take my job, too. That’s the way this thing is designed.”

Kolb is owed a $7 million roster bonus in early March. Unless the Cardinals find a way to land Peyton Manning or Green Bay reserve Matt Flynn, they will have invested $19 million into Kolb by the time the 2012 season commences.

There will be far more pressure on Kolb in Year 2, internally and externally. It will be his make-or-break year in Arizona. He says he welcomes the challenge.

“The Super Bowl motivates me,” Kolb said. “I don’t need motivation from proving people wrong or validating certain moves. For me, it’s winning the Super Bowl and getting that ring on your finger.

“I’m looking forward to the offseason. I think we found a little bit of an identity the past half of the season. Everyone always associated Arizona with an offensive juggernaut, but we have a chance to be a really good, complete team.”

For starters, they’ll feature one of the best No. 2 quarterbacks in the NFL. Only his identity remains a mystery.

When the Cardinals report to training camp next fall, will coach Ken Whisenhunt put the starting-quarterback position up for grabs between Kevin Kolb and John Skelton?

Kolb signed a five-year, $63million contract with Arizona upon being acquired from Philadelphia for cornerback Dominique Rodgers-Cromartie and a second-round draft pick.

But injuries and ineffectiveness left him 2-6 in his eight full games as a starter this season. Skelton, meanwhile, went 6-2 when he started or played most of the game.

After Sunday’s season-ending 23-20 overtime victory over Seattle, Skelton was asked if he felt he deserved a fair shot to unseat Kolb as the Cardinals’ starter next year.

“I hope I do. That is for the coaching staff to determine,” he said, adding, “Kevin and I have a great relationship. We push each other, and we always help each other out. We will see what happens this off-season.”

As the Cardinals cleared out their lockers Monday, Kolb told reporters he fully expects to be in a battle with Skelton for the starting job, saying it only would be fair given how things played out.

He also looks forward to putting this season behind him and getting a clean slate with which to work in 2012.

“I’m looking forward to the fruits of the labor and having a great season next year,” he said.

But Whisenhunt will decide who starts next season and on Monday, he reminded reporters that he’s always had open competitions for starting positions and that won’t be different at quarterback.

“That’s the way we’ve always been,” he said.

When informed of Kolb’s comments about having to earn the starting job again, Whisenhunt nodded appreciatively.

“I would hope that every player thinks he has to earn it,” he said. “… I think you’ve got to have that with your team. You can go back and look at all the spots, and that’s the way we’ve operated no matter what the situation has been.”

Health scares

News surfaced after Sunday’s game that Skelton and wide receiver Larry Fitzgerald each were dealing with some health concerns.

Skelton, who passed for 271 yards and a touchdown, fainted and fell before the game shortly after having his knee drained in the training room.

Fitzgerald took a hit in the third quarter and suffered a bruised lung, which reportedly made him spit up blood at one point.

Doctors checked out both players thoroughly, Whisenhunt said, and allowed them to play.

Whisenhunt said Skelton joked with him about the fainting spell, calling him “Mike,” as in offensive coordinator Mike Miller.

“I knew he was OK after that,” Whisenhunt said.

Skelton said he’s never passed out before and called it a “a freak thing.” He added, “I think everyone was more worried than I was.”

As for Fitzgerald, who caught nine passes for 149 yards, including three big receptions on the team’s winning drive in overtime, he was re-evaluated by doctors after the game and again Monday.

Whisenhunt said everything checked out fine.

Free-agency talk

The Cardinals have several players set to become free agents, including defensive end Calais Campbell, defensive back Richard Marshall, left tackle Levi Brown and kicker Jay Feely.

Campbell likely will be given a multi-year extension or be presented with the franchise tag. Marshall and Feely each said Monday they would prefer to return. And Whisenhunt said he hopes Brown will be back as well, although given what it likely will cost the team to retain him, that might not occur.

What’s next

Whisenhunt said he and his staff will meet for the next week evaluating the team and grading players and each position as well as every play. After that, they will take a break and do it all over again, so as not to make any judgments based on emotion from the season just having ended.

As for any potential coaching changes, Whisenhunt said Monday that it was too early to make any decisions, adding that he must sit down with his own bosses and be evaluated first.

GLENDALE, Ariz. – What a fitting way for the Arizona Cardinals to finish their season.

They win, in overtime of course, with Larry Fitzgerald’s spectacular plays making the difference.

Fitzgerald had two such catches in the game-winning drive, leading to a 28-yard field goal by Jay Feely that gave the Cardinals a 23-20 victory over the Seattle Seahawks on Sunday, Arizona’s fourth overtime victory — all at home — in the last nine weeks of the season. The four overtime wins in a season are an NFL record.

“I wish we could play more games in overtime,” Fitzgerald said. “If we play 16 games in overtime next year, we might go 16-0.”

Fitzgerald made a leaping grab against two defenders early in the drive for a 26-yard gain, but he saved the best for last, a diving, one-handed catch for eight yards that got the team within field goal range and eventually set up the winning score.

“I actually thought it was too far,” quarterback John Skelton said of his throw. “I just saw his arm stick out, stick it, and stick the landing. We come to expect that from Larry. It’s almost like it’s not even a shocker anymore because he does it so often.”

Skelton didn’t mention it, but he fainted in the locker-room before the game after getting fluid drained from a knee.

“Pre-game he scared us all. He fell out and he had a little fainting issue in the locker-room,” Fitzgerald said. “We were all nervous about him being able to play today and he fought through that and was able to go out there and perform and get our team a win. That shows the kind of toughness he has.”

Arizona (8-8) finished the season 7-2 after a six-game losing streak left it 1-6.

“We’re 1-0 in 2012,” coach Ken Whisenhunt said, hoping that the strong second half of the season will propel the team into a successful 2012 campaign.

Seattle (7-9) had rallied to tie the game after trailing 20-10 early in the fourth quarter.

Fitzgerald caught nine passes for 149 yards after one reception for two yards in the first half. It was his 32nd career 100-yard receiving game, sixth this season.

“The performance of Larry Fitzgerald, he is an incredible football player,” Seahawks coach Pete Carroll said. “He is as good as you can get in this game and he showed it. I just marvel at the things he does. He has done it before and he did it again and it proves who he is.”

Fitzgerald joined Jerry Rice, Randy Moss and Marvin Harrison as the only players to top 1,400 yards receiving in four seasons.

Skelton completed 22 of 40 for 271 yards and a touchdown with one interception for Arizona. Tarvaris Jackson was 21 of 35 for 222 yards and a touchdown with one pick for the Seahawks.

The Cardinals earlier had overtime victories over St. Louis, Dallas and Cleveland. The Seahawks finished with the same record as a year ago, when 7-9 was good enough to win the NFC West.

“We know we have a better team this year,” Seattle safety Earl Thomas said. “We are young but the experience that we got this year and all the plays we made we can build on that next year.”

Arizona’s Patrick Peterson, who made the Pro Bowl on special teams as a rookie, returned a punt 42 yards to set up a field goal, then blocked Steven Hauschka’s 24-yard field goal attempt. It was the NFL-leading fifth blocked field goal for the Cardinals, two of them by Peterson.

Seattle won the toss heading into overtime, and Leon Washington’s 47-yard kickoff return gave the Seahawks the ball at their own 40, but they failed to move it and had to punt.

Arizona’s game-winning drive started at the 19. On third-and-3 at the 26, Skelton threw over the middle to Fitzgerald, who caught it between two defenders for a 26-yard gain to the Seahawks 48. Skelton’s quarterback sneak on fourth and less than a yard gave Arizona a first down at the Seattle 37.

Arizona had it second-and-9 at the 36 when Skelton threw toward but not particularly close to Fitzgerald, who somehow gathered in the ball with one hand and cradled it as he fell to the ground. A review confirmed that it was a catch. LaRod Stephens-Howling, filling in for the injured Beanie Wells, rushed three times to the Seattle nine, and Feely’s third field goal of the game gave the Cardinals the win.

Down 20-10 early in the fourth quarter, Seattle tied with a pair of big plays by two rookies, Richard Sherman and Lockette. First, Sherman stepped in front of intended receiver Andre Roberts for an interception that set up a chip shot field goal by Hauschka, then Jackson lofted the long pass to Lockette, who beat cornerback Marshay Green, and it was 20-20 with 7:47 remaining. Green had just been activated from the practice squad on Saturday.

After Washington’s 48-yard touchdown run tied it at 10-10 with 10:56 to go in the third quarter, the Cardinals went 80 yards in eight plays. Skelton was 6 for 6 for 70 yards, capped by a 13-yard TD toss to Todd Heap, the tight end’s first score in an injury-plagued first season with Arizona, putting the Cardinals up 17-10.

Skelton’s 42-yard pass to Fitzgerald led to Feely’s 43-yard field goal that boosted the lead to 20-10 12:18 to play.

Seattle responded, driving from its 20 to the Arizona 6. But the offence stalled, and Peterson rushed untouched from the end to block the short field goal try.

Peterson, who had been slowed in practice all week by a strained Achilles tendon, nearly broke free for what would have been an NFL record fifth punt return for a touchdown. Instead, punter Jon Ryan tripped him up at the Seattle 31. Still, the 42-yard return set up Feely’s 41-yard field goal that put Arizona up 10-3 with 3:28 left in the first half.

Wells was a surprise inactive. He had been listed as questionable but had played through the pain in his left knee through the season.

Skelton finished 5-2 as a starter, 6-2 if you count the San Francisco game.

Quarterback Kevin Kolb missed the final three games of his frustrating first season with Arizona because of a concussion, the result of a knee to the head on the Cardinals’ third play of the game against San Francisco on Dec. 11. He missed four games earlier in the season with a right turf toe injury.

Notes: Marshawn Lynch’s string of 11 straight games with a touchdown came to an end. … Peterson set an NFL rookie record for punt return yards (699), the second-most of any player in league history. … Seattle’s Doug Baldwin became the first undrafted rookie free agent to lead his team in receptions and yards receiving since Bill Groman of did it for the Houston Oilers in 1960. … The University of Phoenix Stadium roof was closed even though it was sunny and 28 C outside. … The stadium already had extra seats installed for Monday night’s Fiesta Bowl matchup between Oklahoma State and Stanford.

NEW YORK — Arizona Cardinals defensive tackle Darnell Dockett has been fined $15,000 by the NFL for hitting Cincinnati quarterback Andy Dalton below the knees last weekend and another $15,000 for a horse-collar tackle on Bengals running back Bernard Scott.

Dockett was called for 15-yard penalties on each play in the Cardinals’ 23-16 loss last Saturday.

Washington Redskins safety Reed Doughty was fined $15,000 by the league on Friday for striking Minnesota’s Christian Ponder in the head and neck area as the quarterback slid. Houston Texans defensive end J.J. Watt received a similar fine for hitting Indianapolis quarterback Dan Orlovsky below the knee.

Atlanta Falcons linebacker Curtis Lofton was fined $15,000 for unnecessary roughness for striking New Orleans wide receiver Marques Colston, deemed a defenseless player, in the head and neck area Monday night.
