Prediction: Kevin Kolb
 
Kolb, brought over from Philadelphia before the 2011 season, hasn't been the next coming of Kurt Warner. He's barely been the next coming of Jake Plummer. However, 2011 was arguably Kolb's best season as a pro—playing in nine games, throwing nine touchdowns to eight interceptions and posting a 81.1 QB rating.
John Skelton, drafted in the fifth round of the 2010 draft, subbed in for Kolb last year and looked decent at times—11 touchdowns, 14 interceptions and a 68.9 QB rating in eight games. While the stats are worse than Kolb's, the results were not. Skelton was 6-2 as a starter while Kolb was 2-6.
Yet, wins notwithstanding, this looks like Kolb's job to lose. Outside of arm strength, he clearly has better physical tools than Skelton and is far more efficient moving the ball down the field. Skelton, who has problems with accuracy, can kill drives even when he's making all the right decisions—which is rare in and of itself.
If Kolb doesn't win this battle, or falters early on in the season, it should be a quick hook and could mean the end of Kolb's legitimate chances as a starter.
