I disagree. I don't think Reggie Bush is going to have that big of an impact in the NFL, and I don't think on the Vikings. I'm plenty happy with Mewelde Moore at RB. Every game that he's started in his NFL career he has had over 100 total yards, and yesterday he got his first TD of his career. The lack of TDs is more coaching too, as he has shown that he has the ability to bust 15 or 20 yard runs, they just don't run him in the red zone.
If we would take a RB, I'd be much happier with Lawrence Maroney. Maybe it's because I'm a MN homer, but he think he's a much better runner. The run/catch kind of guys that aren't pure RBs don't tend to go as good in the NFL. But I don't know, I'm no expert, that's just me.
