Cincinnati @ South Florida: Both receiver and defender are running along the sideline on a deep route, with defender leading the way. The receiver ran up the back of the defender and the covering official threw his flag. Both A and B players were actually OOB when the contact occured. DPI was the call. Pass was overthrown and incomplete, arguably uncatchable. Can you have a PI foul when one or both players are OOB? Note: The contact did not cuase them to be OOB.
