Bouk was a high draft pick he had to go. Especially because he's a head case. He might have screwed up again at UConn and missed his chance at guaranteed money. Hawk obviously had to go, lottery pick. Andre had to go because if he came back and still couldn't shoot, my guess is the NBA decides he can't be fixed. This was his opportunity coming off the NC run. Adama is from Mali. He couldn't improve more here or showcase the PF skills he needs to make $ and help his family. Had to start with his pro career and becoming what the NBA wants.
How does it help UConn? In each case, UConn is better off if they come back, and yet Dan and staff showcased those guys in ways that made them look good. Hawk showed his ability to come of screens and score in guarded situations. Andre got enough time playing PG, and we found those cuts and dunks for him. With Sanogo, he could have and should have done it sooner. He switched things up during our losing streak, letting him get the ball further out, face the hoop, make passes and dribble plus guard wings in space. All of it made them and us much better.
Next year, our team is probably better off if Castle is a SF and not a PG, but he's going to play enough PG to show the NBA guys he can. Clingan is going to shoot enough 3s, maybe put the ball on the floor (??) and show his passing ability. Karaban is going to attack the rim off the bounce and show he can score in traffic, probably will play a little 3 to show he can guard quicker smaller guys in space. That is what the NBA needs to know reas
