One of four things happens:
1) He reverts to hesitation and lower aggressiveness and very little contribution, due mainly to MSU's vastly better than Bama defense and their focusing on him after his outburst.
2) He is overly confident and tries to force things, resulting in errors, turnovers, fouls, missed shots and very little contribution.
3) He shows us signs of what we just saw, but somewhat dampened because MSU's defense is leagues better than Bama, and they will be focusing on him more than had he not just had that kind of game. In this scenario, he scores something like 12-14 pts and has 4-5 rebounds, which I'd take all day long.
4) He blows up again with 20+ points and looks like Bama all over again.
I'd say the most likely outcome will be #1 or #3, 50/50.
