I'm going to partially agree with you.
Bush is a more explosive halfback. He's the type of guy who is capable of taking it to the hole everytime he touches the rock, and his versitility to play HB, WR and KR/PR is not to be ignored. I think he's the type to put up routine 1,400 yard seasons in terms of All Purpose Yards.
However, I truly believe Peterson is the better pure HB of the two. He's never had to share the load at Oklahoma, and from Day 1 when he stepped foot on campus in Norman, he was mature beyond his years. I see him being a Larry Johnson type, who will be able to carry the rock 30 times a game and get you a buck fifty on the ground and will get you 1,500 yards per season.
It all depends on what your tastes are. I think if you're looking for the Earl Campbell type back, who you can build your offense as a running team around, you take AP. Bush, on the other hand, is the type that if your looking for a run and gun, air it out type offense, Bush is your guy.
Also, what durability issues? The guy suffered two freak injuries. Find me one HB in the NFL who hasn't suffered some kind of injury, severe or non severe, and I'll point you in the direction of the practice squad guy who's parked on the furthest depths of the bench.
Look, Frank Gore had durability issues coming out of college. The guy had two blown knees and was one good hit away from having his career turn in to KiJana Carter's quickly. Trust me, that is an injury history to look at, moreso than a collarbone break and an ankle injury. Yet, in spite of this, he's been durable thus far, and the 49ers sure haven't regretted it. I think the same can be said for Peterson, and anyone who selects him. I hope it's Houston.
Also, why is Gary Kubiak's "draft history" being drug in to this? Since when do offensive coordinators have major say on who teams draft?
It's not just talent bro. It's about team individual need.
Matt Leinart had a hell of a Combine last year, and had the resume coming out of USC that were as good as any QBs of recent memory. Yet, he fell to 10. Not because he was injured and surely not because he lacked talent. It was because of need.
Just looking at this year's draft, there's really only one team in the top 8 that I think COULD go HB besides Houston, and that's Cleveland who also happens to need a QB. It's very realistic that Peterson could go to Houston at 8, regardless of how good he performs at the Combine.
