At first glance, I think you may have usage and minute problems with this team. There are only two full time scorers, and with Rodman, Bird, and Walton all being part time players, Wilt isn't going to get much help on the boards either.
I guess minutes are OK after a second look ... if you play your deep bench guys, which is a bit of a drawback (though in exhibition play, it might not come to that much). I still think the usage issues apply, however. Looks like McMillan plays SF at least some of the time, which means weak rebounding overall, perhaps even when Rodman is in with him. This particular Wilt version is surprisingly ordinary.
Still, it'd be an interesting experiment for an exhibition league. This team would have to win defensively because it looks like it would struggle on offense.
