Celtics fan are really taking this hard.
I am going to assume it has more to do with Ray Allen going to Heat, than Ray Allen just leaving the franchise. I think if he would have went to the Grizzlies no one would have cared.
Celtics fans have to have some team to hate and they have chosen that team to be the Heat, so Allen going there sort of twisted the knife in their back especially when they were so close to beating them.
I must admit this is more creative than the Judas Shuttleworth tees.
It is hilarious and disturbing at the same damn time.
