I think it's interesting that someone else agrees with me on the Raiders taking a LT (See Rock's 2009 NFL Mock. Yes, shameless plug). His going for speed mentality is taking way to serious.
Anyway, I wouldn't mind it that much, although I never knew that he was seen as a top 5 talent. The RB class from last year was really strong, maybe he's trying to get one of these guys for himself.
The biggest problem is a luxury one though. What on earth do we want to do with all these RBs. Trade them for draft picks? I'm pretty sure we can't get alot more than a 3rd, maybe a 2nd for Grant after his okay season last year. He would be the odd-man out in this scenario though, I recon. His contract won't make it any easier either.
It is a risky pick though. If he pans out like a Matt Fort, Steve Slaton or a Chris Johnson, he'll be a genius and get another year at the wheel. If he pans out like Darren McFadden did in his first year and a player like Orakpo or Raji is wreaking havoc for another team, he can better start packing his bags.
