LOL. Even within those parameters, there are much better options than Homan.
It's got to be Fizer or Tinsley, though. If there's one trait that defines Fred's coaching style (other than being completely awesome), it's that he takes the best talent he can, regardless of their position, and designs a system around them.
I think Fred would pick someone who adds something the team doesn't have. I don't think he would pick someone who would steal the limelight from the guys he already wants as stars. So, I read the OP as asking what player would make these players even better.
Hence, Homan. He would get big defenders caught up in physical play and maybe even get them into foul trouble. He would protect the lane so other guys could over-pursue on defense. He would keep rebounds alive on the offensive end. He wouldn't take anything away from anyone, except maybe Edozie. Can you imagine Homan and McKay playing together for 10 minutes per game? Our guards would go wild.
