Really hard to speculate until you know who returns and who leaves. We're oversigned, something Painter had never done. So one would think he KNOWS someone is transferring.
Furst has been mentioned - also has been said he loves Purdue regardless of his role and cares more about his degree. Brother on the team. No one really knows
Colvin - legacy player who hasn't played that much this year, once again no one really knows
Waddell - would hurt the least, but would Painter essentially pull a scholly from the son of a former teammate? No one really knows
Gillis - does he come back on NIL as a walk-on? Do we really deny him if he wants to come back? No one really knows.
TKR - he starts, but doesn't finish, and doesn't get a ton of minutes. Is Painter trying to keep him happy because he's the 5 next year, but he's thinking about it?
Berg - is he ever really going to see the floor outside of garbage minutes? Could he start at a MAC school?
After Smith and Loyer, it's really hard to say ANYONE will for sure be back next year. Maybe Heide with his increased mins lately. But if Catchings is the instant starter at the 4. TKR stays and is the 5. You literally have Heide, Colvin, and all the frosh guards going after the same mins.
