We lost Josh Smith to the NBA, like you said.
We lost Robert Rothbart to the European pros. He doesn't sound like he'll be missed at all. The incoming class did a little tour around the state playing in Fort Wayne, Indy, South Bend, etc....and from what I hear they said Rothbart was not that solid and he wasn't meshing well. He would never return calls etc.; he wasn't going to be a great teammate. Good riddance to him.
Those are the only 2 we lost, and they both went to a pro league. That's A LOT of prospects.
