We have a lot of depth this year. If the kid is not going to get second team reps or play on several special teams units, most likely there is no need to burn the redshirt. CJ is the most likely, as he likely will get second team reps. Maybe, if we think a kid could compete for 2-deep position next year, it might not hurt to let them play special teams this year and get their feet wet.
Eligibility wise there are some holes in the freshman/sophomore LB classes, and we brought in 4 LB's this year. At least 1 will likely play, special teams and get some developmental reps in practice. Morris might be the most mature of LB's giving his an advantage.
Possible we could see a RB. However, with Coker's injury that will hurts is development, even if its just a few weeks. He will essentially miss most of camp. Johnson has been out of football for awhile, coaches might want to ease him back in. If either show they are capable, I'm for letting them play.
If a Safety recruit is physically ready to play, there might be a chance to get on the field some with special teams and get there feet wet to compete for a 2-deep spot next year.
