Not sure what you are getting at here. An ACL is not an injury you can safe guard against. Its just one of those injuries. You've seen it in footy how it can be done so easily and innocently, just by changing direction. If its anyones fault its the leagues for trying to get so many games into a short amount of time. Rose's injury is not an isolated incident. He had played 97% of all his 308 games since high school up until this season.
I am equally unhappy as you being as big a bulls fan but you can't go blaming a coach for having his star player playing during playoffs.
You say sit him while the game is control. Well with missing so many games, especially so close to playoffs, how is Rose supposed to get match fitness back, how is he supposed to get his touch back. Wait until we play Miami in ECF? Playing an out of form Philly was a perfect opportunity to Rose get some form.
This is a sad day for the NBA but really is just one of those freak injuries.
