Sports Illustrated Potential 2012 All-Pro Team Rams

RB | Steven Jackson | St. Louis Rams
You'll never guess how old Jackson is right now. I'd have guessed 26 had I not looked it up. Nope. He just turned 24 last month. He's the type of versatile back who will dominate the position in the next generation -- and he'll be helped by the selfless play of our 2012 fullback ...

FB | Brian Leonard | St. Louis Rams
What's the definition of a good fullback as the NFL nears its 100th birthday? Two things: He's got be an unselfish blocker, and he's got to be able to get you some tough yards -- rushing or receiving -- on third down. Leonard will prove great at both.
