The preseason -- a five-game affair for the Cardinals -- can be deceptive. Kolb's problems are tied to an offensive line that's floating adrift. It doesn't help that running backs Beanie Wells and Ryan Williams haven't played a down against a live opponent. These are factors, but Kolb's inability to spark the Cardinals' offense to attack -- it seems to sink into a daze behind him -- is a lingering problem.
Whoever starts the season as the No. 1 quarterback likely will be replaced at some point, but Kolb presents a unique dilemma. You either start Kolb to justify the expensive trade that brought him to Arizona, or you bench him and wonder what could have been (although curiosity is waning on that front).
