Given the investment that the Arizona Cardinals made in Kevin Kolb, you can understand why the team and coaching staff wants him to succeed as the starting quarterback. At some point, though, you just have to accept that things aren't going to work out.
Kolb has two huge strikes against him from ever being a capable NFL quarterback. The first is consistency. If you look at the numbers throughout his career, Kolb is the definition of mediocrity.
In 34 games played, Kolb has completed 59.5 percent of his passes, thrown 28 touchdowns, 25 interceptions, fumbled the ball 16 times and averages 6.90 yards per attempt.
If you are happy with middling production at the most important position on the field, Kolb is definitely the right player for you.
The second and more important strike against Kolb is his injury history. Even in the games where Kolb looks like he has things figured out, odds are good it won't last because he is unable to stay on the field.
Kolb's most recent injury to his sternum and shoulder, according to Jason La Canfora of CBS Sports, leaves the Cardinals turning back to John Skelton.

If this were just an isolated incident with Kolb, you could probably blame it on a bad offensive line or lack of running game, as La Canfora points out.
Who should be the Cardinals' starting QB?
However, Kolb has never been able to stay on the field. When he was given the Philadelphia Eagles' starting quarterback job two years ago, he was knocked out in the season opener with a concussion thanks to Green Bay Backers linebacker Clay Matthews.
Last year, in his first season with the Cardinals, Kolb suffered through a foot injury that kept him out of four games and then left a game against the San Francisco 49ers two weeks after he came back with another head injury.
The inherent risk of using Kolb as a starting quarterback far outweighs the reward. He doesn't do enough when he is on the field to justify being a starter, nor does he stay on the field long enough to develop any rapport with his receivers.
We have seen numerous times what happens to teams when there is constant movement at the quarterback position. The Cardinals need Skelton to stay healthy and at least provide some relief, because his upside at this point is much greater than Kolb's.
As for Kolb, he is a perfectly fine backup, but when you start to expect more out of him than that, you are going to get burned.
