Disagree completely. I think defensive penalties should have sting to them, otherwise they start getting baked into defensive strategy, just like has already happened with PI. With PI being limited to 15 yards in college it’s often instructed to DBs to interfere if they’re burned on a big play. That’s just bad football. I love the NFL rule where PI is a 15 yard penalty minimum and a spot foul after that. You take the auto first down out of the equation on defensive holding and that too is just going to get baked into defensive strategy.
As far as “holding away from the play”, how do you even know it was supposed to be away from the play? As far as anyone knows, the player that was held was the primary target, but because of the holding the receiver didn’t get open, so the QB had to throw somewhere else, therefore “away from the play”.
