Reggie Bush is the highest rated RB prospect to come out of college in like 2 decades according to some scouting services. Thus, I went with him. AD will be awesome too, but I think Bush is more elusive, has better vision, start/stop ability and amazing acceleration. At times it seemed like Bush was Neo from the Matrix running 100 times faster than everyone else. There's only a handful of people that I've ever gotten that feeling from watching them play. Michael Vick is another one that comes to mind as well. AD has great top line speed no doubt and runs with wreckless abandon, but right now Bush is the better prospect.

Speed and quickness kill in the NFL. Bush trumps Peterson in both categories.
Instincts are also important, but I've seen nothing to suggest that Bush is lacking in that category.
Having been field level for a few of A. Peterson's game, I feel confident in stating the talent gap between Bush and Peterson is not nearly as wide as some are suggesting. NOBODY that size has any business being that fast and strong. I know this much. I would much rather chase and grab Bush in the second half versus putting my pads on Peterson's thighs, which is the difference. They are different players with different body types and, yes, I am fully aware of the rumor that Bush allegedly posted the highest predraft grade for a RB since B. Jackson. Bush for a man his size and skill set is amazing. He is a once in a generation player. I would not argue that point. Peterson is not that back. He is a different body type with a completely different skill set. What is to say, though, that Peterson does not or cannot rate as high with his skill set?
Peterson has not played this season yet. Placing a grade upon him at this point is putting the cart before the horse. Give him the benefit of the doubt and 12 more games. How about two healthy ankles? Let him have those for 12 more games. Then, look back into human intangibles, maturation and statistics.
Considering he is an underclassman, there is not going to be anything formal or forward facing coming out about him in regards to how or what NFL teams feel about him; his abilities or chances of coming out this early in the year. That type of BS starts flying this early on and campus gets closed to guilty parties, scouts.
I figure
if OU is in the running for the Big 12 and BCS
then more formal yet off record comments come in December or they come after Peterson petitions the league/NCAA for their letter of recommendation regarding his perceived draft status. At that point the cat is out of the bag and you will start getting the contemporary comparisons or historical references, like Peterson is another E. Dickerson; has tangibles in line with E. Campbell or rates at or above M. Allen. Peterson is not going to be gauged and measured against players with a smaller yet highly dynamic body type...like Bush, Sanders or Faulk...when NFL talent evaluators begin to endorse him.
This is the same kid that had one of the longest and largest college recruiting campaigns...ever...in high school history. It is the same kid that Brown lost to his arch rival and damn near got fired over it. It is the same kid that, when healthy and with an experienced line, nearly won a Heisman...as a freshman.
He'll get the same run and gloss that Bush got. Much of that has to do with a school's athletic department and trust OU is going to make sure EVERYONE remembers this kid. If OU rolls Texas and Peterson has anything to do with it, then it will be on for the rest of the year.
PPR and combined yardage league...Bush
All other leagues...Peterson
