Its something that is very painful to see happening.Former Dallas Cowboys receiver and Pro Football Hall of Famer Michael Irvin, speaking to The Dallas Morning News at his football camp, said: You can let it beat you, or you can rally together and say, Not on my watch.And thats what the community in Dallas Im sure will say, Not on my watch, Irvin said.
