How many running backs does it take to make a successful team? If you’re Mike Shanahan, I'm not sure because I can't count that high. If you’re a fantasy owner, the answer’s usually about three solid backs. There are always injury concerns with every running back – as a July DUI charge. He isn't likely to be suspended during the NFL season, but the Seahawks could have him on a short leash if he does struggle. I'm not sure I trust him with a first or high second round pick.

7. Steven Jackson - St. Louis Rams
Projected Stats: 1264.7 rushing yards, 6.6 rushing TDs, 276.0 receiving yards, 0.7 receiving TDs
Projected Points: 192.87
"Hey smart one," I can hear you saying sarcastically through my magic Sports Writer powers. "ESPN has Jackson all the way down at #13 on their top 300? Do you think you know better than them?" Well, not saying that ESPN's wrong, but there's a good deal of stats to back me up. For instance, who's the only guy with over 1000 yards rushing every year since 2005? S-Jax. Who hasn't missed more than two games combined the past three seasons? S-Jax. Who is only actually 29 years old, despite everybody knocking him due to perceived "age issues"? S-Jax. Who has at least 300 receiving yards in each of his past four seasons as an extra bonus? I don't even think I have to say it at this point. The only possible argument for knocking down Jackson is that his team won't offer him much in the way of help (entirely true). But the fact that he's easily the best offensive player could help in this case - the Rams can't afford to not get the ball in his hands 20+ times a game.

6. Chris Johnson - Tennessee Titans
Projected Stats: 1246.7 rushing yards, 7.1 rushing TDs, 314.4 receiving yards, 1.0 receiving TDs
Projected Points: 199.51
There's a lot of breath wasted on whether Chris Johnson can get back to his "Old Form", as if his 2011 season consisted of him tripping over Matt Hasselbeck's feet every time he got the ball and rolling around helplessly on the ground. That gives off a sorely wrong impression of Johnson. In fact, here was his actual 2011 stats in a vacuum: 16 games started 1047 rushing yards, 418 receiving yards, 4 total touchdowns. Not bad for a potential number two back on your fantasy team, right? At the very least, he didn't fall flat on his face like some people think; he was still serviceable. But the numbers indicate that was an outlier: his -0.21 NEP per play and 29% success rate on increasing the Titans' scoring chances were easily the worst totals of his four year career. There's no reason to think that he won't get back to form - maybe not his 2000-yard form of 2009, but likely somewhere in a happy middle yardage-wise. Even the touchdown total seems to be a fluke. Before putting up eight rushing touchdowns last year, the Titans as a team hadn't had below 13 rushing scores since 2005, when Chris Brown (not that Chris Brown) was their starting RB.
