Eddie George starts every week. Period. Once again, don't sit you're best running back based on a matchup.
Now the next three, that's a different story. Henry may have appeared out of nowhere to some of you, but he's a solid, Division 1A RB who got lost in Buffalo's crouded backfield last year. The Vikings defense is the worst, and he could bust them up. The Edge is facing a very tough Dolphin defense and is still recovering from the knee injury. I would sit him this week.
This brings us to Fred Taylor. Arguably, he's one of the top three backs in the league talent wise. If he started every game for his first 4 seasons instead of sitting down for half of them, there would be no debate here. He's a great runningback when he's healthy and has had a good amount of reps.
So I personally would start Taylor and George. But you've got such a deep RB corps, you can start anyone. Watch Henry bust out a huge year. He's ready.
