Crackback block

[TXMike]

Complete agreement with both of you. Those guys in motion towards the ball are very good candidates to foul. And re turning the back, at first I was going to say it is almost impossible to have a block in the back on the crackback situation because the defenders are usualy square with the LOS or running straight at the impending blocker. But as I thought about it more I remembered plays where the "crackback" guy did end up in a position where he was behind the defender and then blocked him in the back, towards the LOS.
