I can't see someone like Keene transferring. He's got national noise right now and if he's not NBA material, what does going to SU get him? Unless he thinks JAB can better hook him up with an overseas league or he wants to get into coaching.
It gets him the chance to play home games in front of 25-30K fans, play at Cameron and MSG, and very likely play in the NCAAT with a much better shot at a deep run than if he stays put.
Put another way: it gives him a chance to play the most meaningful basketball he's ever going to play.
