We're going to need somebody. Gotta have 2 legit bigs that can contend defensively with teams like the Pels Clips Spurs Blazers Thunder Grizzlies and Bulls if we expect to win a ring. And don't throw out Black and Dorsey because those two guys will get chewed up by the likes of the teams I just named.
If you're a Rockets fan, you should know that Ainge represents more than just a somebody that played back in the days. Hint: Ellie.
All you need to know about Ainge is that he would have been happy playing for the Jazz. (And I'm not talking about his religion.)
