had one a few year back, Tailback took a pitch and then threw a pass after the pass was thrown defender nailed the Tailback, I had flag for roughing the passer, the DC went nuts screaming and hollering he not the QB you can not call Roughing the QB, I told him I did not call roughing the QB I called it roughing the passer. it was a great moment when the lightbulb clicked on in his head when he realized that the rule stated passer and not QB
