If he can stay healthy - and that's a big if - I believe he has the potential to be one the best to ever play the position. He is simply an amazing athlete. But it's hard to stay healthy in this sport, and with his history of past injuries... Only time can tell.
But he is definitely the real deal and I look forward to watching his performances for as long as he's around.
The hype about AP's injury history is so overplayed. He has had a series of freak injuries that have little to do with his running style. Here is a summary of his injuries.
2004:
Oklahoma played 13 games. Peterson played in everyone of them. He started 8. He ran for 2040 yds on 339 carries for over 6 yards a carry and 15 TDs.
2005:
Oklahoma played 12 games. Peterson played in 11 of them. He started 8 games, and played only part of 3 games. He ran for 1195 yards on 220 carries for almost 5.5 yards per carry & 14 TDs. He only got 11 carries in the 3 games, so for argument sake I'll say he really only played in 9 of the 12 games. His injury? An ankle sprain. So rare for a RB. A devastating injury they said. One that is impossible to comeback from, and that plagues football players for years......... Didn't happen.
2006:
Heisman contender for the first 6 games until he got hurt on a freak play where he dove into the endzone and broke his collarbone. We are talking about a collarbone breaking. The definition of a freak injury. Up until then, he averaged 5.85 yards a carry.
2007:
Was solid in his first 3 games averaging 21 carries and 90 yards a game. Broke out against Green Bay and averaged nearly 10 yards a carry on 12 carries in the first half. Brad Childress kept him out of the 2nd half of the game and fans were very upset. Took the reigns off the next week vs the Bears and AP broke out for 224 yards on 20 carries. Had two mediocre games the next 2 weeks, then set the NFL rushing record against the Chargers. The following week against the Vikings most bitter rival, the Green Bay Packers defensive players putting out bounties to each other to keep him under 100 yards. The Vikings had a historically bad game and in the 3rd quarter Al Harris (desperate to hold AP under 100 yards in a game they were absolutely dominating) over zealously dove at AP's knee from behind and to the side when AP was making a cut. If that is not a freak occurrence I don't know what is. The result was that he tore the ligament in his knee that keeps it from bending outward. He was back in practice about 10 days later, and would have played after missing one game had it been a playoff game. And this is with a coach that is very conservative and is doing everything to protect AP.
These are not signs of chronic injuries such as pulled muscles, they are bones breaking and ligaments tearing. If someone hits you in a bad way your bones and ligaments are only made to give so much. Hamstring/Joint/Groin problems would indicated he is injury prone.
Running backs do have a short shelf life in the NFL but AP's past injuries don't indicate at all that he will have a short career.
