Bobcats will have some big shoes to fill. Brazil, Harden, Keller and Flading and others are huge shoes to fill. Those guys aren't gonna be replaced in one recruiting class. I would be really impressed if we can win atleast 8 games considering the losses to graduation. Tettleton will be better but won't have as much established weapons to work with. The offensive line is a huge? Can they buy Tettleton enough time for him to make a play like they did this year.
WR - A big chunk of the receiving corp is gone - Brazil, Dunlop, and Gross. I don't think the subs are at the same level, so I share your concern there.
RB - I have mixed emotions here. Harden was good, and had a good year, but Boykin and Blankenship both have another year to develop, plus Dallas Brown will play. I think RB will be OK.
OL - The OL will indeed be huge, but not so much a huge ?. Prior appears to be a solid replacement for Strum, and McGrath should do well replacing Flading, and the other three positions all return starters.
LB - The losses of Benjamin and Keller are big, no doubt. Reallly, though, OLB looks solid with players like Woseley, Lewis, Grady, Moore, and Jones returning, plus Jovan Johnson coming off a redshirt. At MLB I don't have a clue who will replace Keller, though. Stefanski? Morales? Russel? Tim Edmond? I think at least one of them will step up, though, and play OK, so I'm not too concerned.
