1. Michael Bush
Like Harrison, someone has to carry the ball for the Raiders, and McFadden has been disappointing. Bush is a tougher inside runner, so don't be surprised if he starts seeing the bulk of the carries midway through the season. He's a better waiver wire option than a draft day selection, but keep your eye on him for the first couple weeks.
2. Arian Foster
Houston's backfield situation is a fantasy disaster, but with Ben Tate out of the way and Steve Slaton likely to see the field mostly on 3rd down, Foster will get a chance to be the guy. The Texans are still going to throw it a little too much for him to see a ton of carries even if he does emerge as the full-time starter, but for a few weeks at least he'll get his chances.
3. LaDainian Tomlinson
Yes, he's washed up and clearly Shonn Greene's backup. However, the Jets ran it over 600 times last year. Even if Greene gets 350 carries, there's still plenty to be had. He's a deep sleeper, but if he can make the most of his touches behind a terrific O-line, he's worth a late round draft choice.
