Chuba will need to return. He's killed his NFL stock this season, and either needs to prove last season wasn't a fluke, or he'll need to give up on NFL dreams. I could actually see LD or Dez going to the NFL this season before Chuba.
I think we have a number of guys on the defensive side that could go the NFL route and don't need another season.
Rodarius Williams should be a pretty solid NFL lock.
Bundage, Amen, Rodriguez, and Harper seem like late round or UDFA guys, and I'm not sure how staying another season will improve that.
Jenkins could be a higher pick on the OL, but Sills might actually benefit from another year.
In the WR group, Tylan needs to go get paid while he can. Stoner and Wolf should return.
So from that group, here's what I think will happen.
Should go
Jenkins
Rodarius Williams
Tylan Wallace
Could go, but another year wouldn't hurt
LD Brown
Bundage
Amen
Rodriguez
Harper
Sills
Need to stay
Stoner
Wolf
Dez
Chuba
