I'm not much of a Texans fan, but I do seem to have great taste in draft picks. Domanick Davis is a great runningback, but your O-Line...well, for lack of a better word, sucks. Bad. Get D'Brickashaw Ferguson as the 1st round pick. You won't regret doing so.
Sorry, but I just don't understand why you would want to draft Reggie Bush. Domanick Davis is more than enough, and Reggie's talent would go to waste, because quite frankly, he's not much better than Domanick.
