Well at this point he should have learned that his almighty offensive system is not so great that it can overcome a poor OL and RB's that are other teams throw aways. The arrogance he showed in not selecting Bush has come back to bite him in the ass. Don't get me wrong his system is a good one but it still takes players of which the Texans do not have enough. Flanagan got killed today, Pitts struggled and Wiegert is below average. Salam is a decent backup but not even an average tackle. If you look accross the NFL, offenses are about as good as their lines measure up. The Texans line is below average and so is the offensive production.
