While true, is that a targeting issue or an officiating issue? I would say it’s the latter.
Take today’s CFP games for example. That PI on the Td drive against Ohio State looked like defensive holding to me (Still an obvious penalty) whereas the play in the first half of the OU-LSU game that had Lincoln Riley going crazy was clear and apparent interference. One gets called PI, the either drew no flag. I wouldn’t call that an issue with the rule, I would call that an issue with crews calling it consistently across the board.
