The best thing this staff could do is get a tall rim protector that can rebound & defend. That would likely help bring Semi back. Right now we have two unproven freshman at the Big position.
I personally feel that if Semi can be a first rounder this year, it would be best for Jank & SMU basketball. In addition to Sterling making a roster. Jank doesn't have a history of sending players to the NBA, and that is one thing he will need to continue to get high quality recruits that have NBA aspirations.
The only way Semi gets projected higher next year is if he develops the skills that will allow him to be a better SF--and that's just getting more athletic and quicker. Either way, I think it will be a win-win for both parties.
