Talking about this sort of thing, the NBA should clean up plays that cause injury. They, the employer, have some obligation as to the well being of the players. they should really add more flagrant rules, since there are usually a few type of plays that get people hurt, and they should discourage that type of play. That is why the clear path foul exists, and flagrant fouls exist, so - the league should develop this a little further. I'll reference Howard knocking Davis out cold with repeated "accidental" elbows to the head not too many years ago. Well, accident or not, if you repeatedly elbow a guy in the head, the player is obligated to try not to do that, and should get called as a flagrant foul, and eventually ejected if it keeps happening. I think there is actually a rule about this, but then they would have to actually take liberty to make the call against one of their special superstar players.
