We've all been marveling at the ferocity with which Minnesota Vikings' running back Adrian Peterson has been attacking his rehabilitation from a torn ACL suffered on Christmas Eve, and the NFL's best running back still insists that he's going to be on the field for the Vikings' Week 1 opener at the Metrodome against the Jacksonville Jaguars.

Minnesota Vikings' head coach Leslie Frazier realizes this, and says that he wants to make sure that his star running back doesn't overdo things.

"He's so valuable to our organization that we have to be smart. We'll tread lightly as far as Week 1 and how much he'll contribute on the field. Even when we get to training camp, he's going to be chomping at the bit but we'll have to be smart."

With as competitive as Adrian Peterson is, there's no doubt that he's going to have the mindset that he can walk into Training Camp later this month and just immediately take over as the #1 guy on the depth chart. While it's entirely possible that he will be #1 on September 9, I would expect Peterson to be extremely limited during the pre-season in order to ensure that happens.
