Yeah, it all boils downs to the $$$ thrown at these guys.
With the Cardinals taking James, yes, it's doubtful they would still draft Williams or White, since Denny Green doesn't have a great history of using 2 backs. He'll probably still draft a RB, but not in Round 1. Teams that I think are still interested in Williams and White are 49ers (#6), Lions (#9), Browns (#12), Ravens (#13). I'm not saying all those teams will draft them, but White and Williams both have chances of solidifying their Top 10 draft status if they have good pro days. If White runs a 4.45 or faster, he's good to go. I don't recall DeAngelo's 40 time, but if it's in the low 4.4 range or lower, then he's still going to get some hard looks.
But I do agree this creates better opportunity for either player to drop to Atlanta at #15.
