As far as who will be the next BMOC for the Men's B-Ball Team, that player is most likely not yet on the roster.
Possibilities:
Mashburn: Probably has the highest potential of anyone on the team. He is a freshman, plays guard on a guard dominate team (with Pitino) and has the most upside ahead of him.
Ihnen: I don't feel like he has really grown into his frame yet to maximize his physical abilities and he hasn't adapted to American basketball yet. He has shown signs of getting it, but his window as a sophomore is already starting to close. He needs to progress this year.
Tre Williams: He is already physically and mentally mature for hoops. I feel like his chance may have already come and gone since Pitino doesn't play him more. Hard to say with another year of Gabe solidly in front of him I don't like his chances.
Mitchell: This guy could be the sleeper! He is rail thin for his frame but has some pretty good physical skills. If they can pack some muscle on to him and red-shirt him he could surprise and grow into a real steal. Really a complete unknown at the moment with a lot of potential.
Gach: If he is the BMOC, it may be the sign of Pitino being shown the door. Not sure he can make the leap like Coffey, Carr and Oturu. We will probably know by the end of the season. Right now he looks like a great second option, not a savior. But then again, he hasn't had to try to put the team on his shoulders yet! He had the same pre-draft experience Carr did so maybe he could do a little Robin to Carr's Batman if needed. If so, he'll try to go to the draft again and may (foolishly) be gone after this one year.
Look for someone who isn't wearing Maroon and Gold yet is my bet.
