So I argue that Brad Childress is right to limit Adrian Peterson to around 20 touches a game. But that doesn't matter, because you don't like me and I don't like you ("I like you." "Fine, you like me, but I don't like you." "Maybe you'd like me if you got to know me."). So don't bother with what I think.
Reuben Frank of SI writes "No rush to use Peterson: Vikings' Childress careful not to burn out rookie." Frank writes of other rookie RBs that have been overused and worn out, and suggests Brad Childress is doing the right thing for the good of the franchise by not selfishly thinking short-term and using up Peterson's ability. It's a sound argument.
You should also take note of what Dr. Z writes in this week's "Power Rankings": "Walter Payton ran angry. So did Emmitt Smith. Adrian Peterson runs angry. And he also has a lightning change of direction and more speed than anyone chasing him has. This is a rare package the Vikes have here. I just hope they don't screw it up." I would suggest one way the Vikes could screw it up is by giving Adrian Peterson 350+ carries as a rookie.
Adrian Peterson is special. Quite possibly all-time great special. He's certainly one of the top running backs in the league right now, and the Vikings' best offensive player, so he should get the ball to help the team win now. But 20-25 touches gives him that chance, and another 10-20 carries for Chester Taylor still helps the Vikings and helps Adrian Peterson stay fresh for a game, for a season, for a career. Herm Edwards rode Larry Johnson for a record 416 carries last season (with another 41 catches); Johnson then stunk in a playoff game and doesn't look the same this season. We can't have that with Adrian Peterson: he's too important.
There's still room for complaint. If Peterson starts getting significantly less than 20 touches a game (as he did against Green Bay), we should wonder what's going on. If Peterson is coming out of the game in the fourth quarter when the game is on the line (as he did against Kansas City and Green Bay), we should wonder what's going on. But if Peterson continues to share carries with Chester Taylor? That's just good football.
