I think maybe Mookie gets some spots to contribute this year. I hope so. He's a good kid for having hung in there, especially with his emotions so much on public display a few times in the past. I wish him the best.
He is a talented guy, and can give us the occasional microwave off the bench. I can see him getting some minutes as the 1/2 guy, especially if Southerland doesn't rebound again this year. Mookie doesn't have to rebound at the 2 to be a designated shooter, he just has to get out on guys, use his 6-6 height and disrupt some passes.
Southerland has to rebound, and was not up to it last year. The 3rd forward will come down to whether Southerland can get 5 rebounds a game as the 3rd guy. If he can, he gets the 3rd forward spot this year.
If he can't, it will go to Christmas for his rebounding and defense. If Christmas is your 3rd Forward, then I can see where Mookie gets the occasional shot at the 2G. Also depends on MCW's development. IF he can defend at this level as a very skinny frosh (like UConn's 2 kids did last year), then Mookie won't play after December 1.
If MCW and Cooney are not physical enough yet to play Big East defense. then Mookie will be the 4th guard and could see time as a zone buster when the other guys are cold. But we won't play a 4th guard very much at all, unless we have Christmas in the front court rotation along with Fab Melo and Baye Keita. That's just too many guys who can't be counted on to score. That would bring Mookie into the mix, potentially. Boeheim probably trusts him a bit by now. He is a senior, after all.
