I get that, I really do but I think Rob has some useful skills. What he doesn't have right now is confidence. That seems clear to me. PT is likely going to help.
IU needs them both, especially with AF out.
Rob is a Jr. going into the heart of the Big Ten schedule and has not done anything in the last 2 years that makes me believe he will somehow transform into a confident good offensive player. He isn't going to learn how to dribble pass shoot and see the court over night. He is a lost cause and the sooner Archie figure that out the better.
