Mullin has to start Owens against centers such as, Chrabascz. He and most B.E. centers will eat up Yakwe. Have you seen Patton on Creighton play - forget about it!
I have not seen enough of them this season to say so they may play him at center but I don't really think of Chrabascz as a center. He's more of an in between SF/PF. Good passer, good shooter. He's definitely a guy who could get either Yakwe or Owens in foul trouble. I'd be more inclined to have Ellison on him except we need someone on Martin who also is an inside/out guy but is a lot more athletic so we have some serious matchup problems.
