I would agree LB was the worst performing position but do think has more depth - Dmo, Ford, Gbenda, Richardson, Brock all performed pretty similarly and all got material playing time. And at least there's some hope here that Ford steps up and Dmo/Gbenda finally learn how to use their athleticism. Then some sleepers like Blackwell (who IT thinks starts), Tillman, etc.
Edge was my #2 worst group last year and only Ovie and Collins are returning with meaningful playing time. I guess Jett Bush too. Collins probably shouldn't even be an edge though. Good incoming class but that probably won't help much this year. So that depth chart is Ovie, maybe Collins, Bush, Barryn Sorrel, and a bunch of True Freshmen.
Safety has Jerrin T, Coffey (who basically hasn't played), and incoming Freshmen. That's really fuckin shallow and our safeties were also bad last year.
So I think edge is the biggest need because it has both no strong starter candidates AND very little depth. LB at least has a chance of serviceable starters in Ford, DMo, even Gbenda, with some experienced/athletic bodies behind them who could be good if the light clicks.
