I'd say the biggest losses will be Jennings, Kennedy, and Bituli.
Crouch and Harrison will be more polished, which will help with losing Bituli.
Brandon Johnson returns after taking a redshirt this year... that will help and I expect Palmer to step up but we'll definitely miss Jennings and Calloway. It's a shame Gilbert isn't coming with Bailey... he could've been our #1 WR as a true freshman.
Not sure who will play center next year, but we have options. Carvin, Calbert, Akporoghene, Johnson, Lampley, Lane... finally some decent bodies on our roster.
Getting Flowers back should help with losing Warrior and we've got some good DBs coming in.
