Franklin a while back already identified Harvey as the 3rd DE, which could change but he's likely in the rotation at least behind DDS and Fisher. And Franklin also implied, along with Losey (S&C), that Kemajou is a go for this season and if he's not redshirting he is playing a good bit. That's already 4 DE's. Then there is Coleman who although only showed up in the summer is making a big positive impression with his speed, twitch, and size. So Coleman is also in the discussion to play and not redshirt, although Franklin and Barnes may prefer to reshirt him as long as one or two of the other young DE's is ready to contribute among Robinson, Mayer, and Williams. There have also been some positive about the other true freshmen Jennings (already close to 250 lbs when he could still be in H.S.) and Harris. Not much on Burnett.
I'm just not that concerned at this point. Lots of young talent that we haven't seen yet, but so many possibilities that DE really may be one of the deepest positions on the team. We didn't see much at all of the young DE's last season but that could have been due to the depth of the rotation with Carter, DDS, Vilbert, and Vanover all itching to get into games. If players like Robinson and Mayer weren't talented and working towards contributing they likely would have transfered last Spring......
