He might be more like Emmitt than DMC? Mental gymnastics aside, AP is not built like 22 who never had a serious leg injury. You point to the outlier and assuming the outliers all got there the same way but there is no reason to imply causality. You are reaching pretty hard. He already has 2000 career carries.
I don't know that DMC makes the roster but between him and the three other guys competing for those two remaining spots, we will have some talented runners.
Tell me who is reaching more. The person who believes a back who has never rushed for under 4 yards a carry in his carry and rushed for 4.5 in his last full season can't do it or the one who believes a back who has averaged less than 3.5 his last three seasons, two backups who've never carried more than 54 times in a season and a back who has never even been close to making it through a season healthy qualify as "some talented runners."
It seems that you want to do everything to discredit that Peterson could succeed here while I'm willing to concede that he might not. His career already shows he's more like Emmitt than DMC, but that doesn't mean he's going to continue to be like Emmitt. There's just evidence to believe that he might. More evidence than there is to believe we could even come close to getting by with those "talented" guys that we've got.
I'm not going to continue on with you on this because it is obvious that you are not being rational about it (even though you apparently believe that you are). If there is anyone else who believes the evidence I've presented is faulty I would love to discuss it with you.
I believe the evidence speaks for itself for anyone willing to listen to it. I don't believe it means that any back will take will fail or that Peterson will succeed, but there are probabilities that can be seen when we look at that evidence that clearly indicate the risks and possible rewards either way that we go.
