Man... I do not see an excellent defender. Certainly solid-plus, when the matchup is right. Provides switchability other slower-footed centers don’t. But an excellent defender to me is someone who makes opposing players think twice about what they’re doing. Change the way they play and have a game altering presence. There isn’t a single person changing up their game because of Rashaun Holmes. And when the other guy is able to muscle him down?
Plus... We’re one of the worst defensive teams in history. It’s hard to justify calling anyone excellent TBH.
