I was watching the BGSU game on TV and the commentator said something about how a CB can look back for the ball and thus become an eligible reciever, nullifying most things that would otherwise be pass interference.
Is this true? Under what conditions does that work?
Also, does the instance Brian highlighted in the Offense UFR stop being PI (under the rules, looked like a weak call to me too) if the CB looks back for the ball?
Someone please explain.
