I think that's the main question when it comes to who the Cards draft at 31. If Whiz likes TH, and i think he does, the focus will shift to C or DE/OLB. If you remember from the pre-season on,Whiz has had nothing but good things to say about TH. He inserted him into the starting role mid-season in a comfortable position to give TH some experience. The results were mixed but you figure with a full year in the program that Hightower will improve. Most of us liked what we saw in Hightower and there's every reason to believe that,with the year experience, he will be a more decisive,patient runner. He's got the size, speed, and vision you like from a RB so i think he's our feature RB next year.
Saying that, unless a Moreno or Wells falls into the Cards lap, they will be drafting Alex Mack or the best DE/OLB(Michael Johnson?) available at 31. They will likely address the RB position in round 2 or 3,and may even take one later on, but a 1st round RB, i don't see it.
