I think people calling for players to hurt Ray don't realize that the players in the Celtics lock room, might have been a bit miffed over Ray not staying, but I still think they like/love him and would never want to see any harm come to him, never mind be the cause of that harm.
I really don't think NBA players, with very few exceptions, wish injury upon each other or want to purposely cause injury to a fellow NBA player. They know what goes around comes around. Do something like that and you put a target on your back and that target could cost you a career and millions of dollars if someone decides to really take you out.
Fans think different than players and I doubt anything like that comes even close to happening to Ray Allen, nor would I want to see it.
