It is unclear why Andrew Bogut has never been altogether healthy since his rookie season six years ago, but there are signposts.

Bogut's last two mishaps - the horrific elbow injury of late 2009-'10 that virtually rendered last season ineffective as well and the broken ankle that will probably keep him out for the rest of this year - were suffered during aggressive moments, such as going hard for a blocked shot.

It is almost impossible to hold aggressive play against a professional athlete, especially in a guaranteed-contract sport that occasionally encourages cruise-control behavior. Bogut usually throws his body around with abandon for a 7-foot center, maybe too recklessly at times given that he doesn't have the grace or agility of a smaller player.
