I wrote earlier that I think this is just good coaching. Kolb knows the speed of the game and has faced NFL defenses that blitz, no reason to dumb it down for him. Manuel on the other hand is being eased into the speed and complexity. If you threw everything at him it could slow his learning curve. The objective is to have him ready for opening day.

And all the men and women merely players:
Where have I heard that before?
How they are handling Kolb vs Manuel strikes me as just good coaching, not subterfuge.
