Yep. Figured there was a semi high chance, higher then other players, that he would transfer, despite maybe being about a possible #2 back up guard that might have gotten about 8 to 19 minutes per game on a team that probably make NCAA Tourny next year.
Also made some sense with him graduating, that he might transfer to a grad program, with a better, more prestigious academic grad program.
And Rapp is easily replaceable, doesn't hurt losing him.
Wish him the best, luck, hope he gets what he looking for.
