Been watching him since he got to OU, and stood in the rain the whole game as he broke the rushing record against Kansas. Perine will have a place somewhere in the NFL, but I think it'll be as part of a committee. Obviously he's got power, and more wiggle than most who look at his body type will realize, but he doesn't have a ton of burst. Over time he started to get phased out at Oklahoma by Mixon for that reason. Perine does everything well. He can catch, block and is a smart and hard worker, but he's just missing that extra gear that top RBs in the NFL have. I don't know if he would add much to the boys that Zeke doesn't already bring and if we're going to spend picks on the position I'd personally prefer someone that offers a different dynamic.
As far as the increased value of RB's, I can't say whether Zeke will make an impact on team's decision making. But based on the crop of backs coming out there will be at least a couple going in the top 20. Most of the draftniks have been salivating over Fournette and Cook for the past two years.
