How does Bosh provide more stability???

He missed 15 games a season.
I would rather have Dirk personally. Outside of one bad game, Dirk is getting close to 30 a night, and will give you great %s. Bosh will also, and more bds, but Dirk's bds should end up at 9ish per game. Bosh doesn't steal or blk at all. Dirk at least gives you the 3's.
It's close, but Bosh is the bigger injury risk. Dallas is not in a groove right now, and Dirk is still putting up big numbers.
