Smith is going to get his points against whoever we put out there Obekpa, Gift .. doesn't matter. But he can't play a full game, is a weak defender in space, and doesn't rebound well. Start a small lineup and make him guard Sampson or Sanchez. Jakarr or Orlando being on the back line of the zone, or even playing him man to man, will do no worse than our "bigs" Obekpa and Gift.
If the plan is to try to shut him down with Obekpa or Gift playing him one on one, we'll end up needing to send double team help and then the Georgetown guards will have a field day. And we'll get no production from Obekpa/Gift on the offensive end. That combination (Gtown guards going off and us not scoring inside) worries me more much more than Josh Smith getting his 16pts.
Let Sanchez or Sampson do the best they can on him, use the zone to deny entry passes, and on the other end make Smith guard one of our guys 15ft from the basket where they can both shoot or drive past him.
