Gbenda is still limited athletically, and while he has been vastly improved under Choate, I believe the starting linebackers coming out of spring even if Gbenda stays will be Anthony Hill and Liona Lefau. The staff is super high on Lefau. Gbenda's best move would be to follow Choate. He will get exposed in the SEC pretty easily.
A starting tandem of Watts (if he stays) and Williams, with Filsaime, McDonald and Rubell as the primary backups, plus Taafe as the glue guy to pair with the younger guys represents an enormous makeover of that room into a suddenly hyper athletic and scary unit.
I doubt Goosby goes anywhere, he is the heir apparent to the LT spot unless Baker takes it from him. Kirkland is doubtful to leave because of the knee injury, but if he does I can't say it would be impactful at this point. Chatman may be a flight risk along with Cojoe, but Stroh is likely going to be a program guy that maximizes at some point and maybe finds a starting job a couple of years down the line. I can't say that losing either Chatman or Cojoe would be felt.
