I think at the end of the season Anderson Varajao was a very good back up to Big Z with the Cavaliers, he will only get better in my mind. But it's hard to disagree with you that Alonzo wasn't the best back up center even though I hate him so much.
Alonzo Mourning would start for pretty much any other team. Before that calf injury, he was cruising and really helping out the Heat. Zo is actually a starter but in his role with the Heat he's easily the best backup any center could have.
I just watched a movie about his rookie year. Apparently in Chinese culture, you're not supposed to dominate your foes. This is probably why he played so softly in his earlier years.
Thats the Yao I like. I loved watching him play and dominate the paint after the All-star break. The great wall of china will rule the NBA once Shaq Daddy retires. He'll be something next year, only if he's aggressive.
