I have thought all along he'd be an adequate fantasy QB. They are not going to run the ball, so by default he'll put up good fantasy numbers.
But he's going to find out what McNabb knew all along. Their offense is predictable, their pass protection is suspect, and it is hard to score in the red zone. I like Andy Reid, but this offense has failed to be consistent for a long time now. Add into that a first year starting QB and I think there are definite growing pains to be expected. Not to mention, I think Kolb is one of the more likely QBs to take some nasty hits/sacks - I'm surprised if he starts 16 games.
