Who guards Simmons in the man-to-man defense? He's a 6'10" small forward who handles the ball well. It won't be Spangler or Lattin. Woodard is too short. Although Cousins is our best defender, you can't be having your PG do that because he goes inside too much. I think it has to be Buddy's assignment and just accept Simmons will get his points. We can't afford to get someone in foul trouble trying to do something that nobody has been able to do.
It will be interesting because OU switches on screens (except for Spangler and Lattin), so you will see times when even Woodard ends up on him. I expect Christian James to be guarding him some. He's quick, strong, and a decent defender.
My current preference would be to shut down the other 4 players and letting Simmons do his thing. If we drop off to double him, he is a good passer. He's only an average outside shooter. JMHO.
