Video: Hear Bob Ryan's reasons for comparing Time Lord to Bill Russell

Remember when Tommy Heinsohn compared Greg Stiemsma to Bill Russell? Well its been quite a while, but we finally have another young center in Boston that is being compared to arguably the greatest player in NBA history. Hear the long time Celtics writer's reasons for paying Robert Williams the ultimate compliment he could receive. Personally if you want to compare Celtics centers, I think Tony Battie is not a bad comp. Williams is even more athletic than "Batman," but Battie had some very solid years for the Celtics. He was no Russell, but no one was.
