I'll assume that Keita, Wilcher, and Lloyd are gone and that next season you start;
Lawrence
Williams
Gary
Mast
TBD
Bench spots:
-Rice. Some rumors of him transferring no idea how credible but I hope he stays because he fits great and I think he's got big upside
-Uhlis. He didn't stick around not to play next season and he's a good second unit/second ball handler option when Williams/Lawrence need a blow
-Hoiberg. Guy will always have a role. Not because his dad but because he's a great 8-10 minute energy guy and can do some shit. Liability if he plays a ton though.
-Diop. Maybe he makes a leap and starts at 5, but seems like an off the bench big for next season.
So the priorities are probably:
1. A big who can play above the rim on both ends. Would be nice if he can do some stuff outside the paint, but I think you need an option to go big and put Mast at the 4
2. A long wing who can give you something on both ends. Needn't be a complete scorer like Brice but that would be extremely nice.
3. A multi year guy who is in the mold of Mast and let's you play 5 out.
Obviously bench/starting spots play out differently depending on who you land
