If Yao can get some rest in the off season, I would say yes. OR he fakes a injury next season for a few weeks or a month to rest, that'll work too.
Yao has been a monster on the boards lately, with a 21 and an 18 board game in the past five days. He is only five boards under averaging 10 a night and if he is able to play an entire season without pain, he may very well average 12 a game.
Of those players who play more than 30 mins/game, Yao is now 8th in rb/48 mins. The top ten is: Camby Dwight Howard Ben Wallace Duncan Jamaal Magloire Samuel Dalembert KG Yao Okafor Marion He has just 0.5 rebound per 48 mins less than KG.
12+ is too much. I'd love to see it but that's a crazy amount of rebounds. Even Shaq had trouble doing it year in and year out. Yao is a lot less moblie. Height isn't nearly as important to rebounding as mobility, positioning, and just flat out desire for the ball. Hopefully, Yao proves me wrong.
