if we didn't want refs influencing the game we'd self-regulate.
except we can't.
so we ask refs to influence the game with calls. early, late, whenever. not calling a penalty late IS INFLUENCING THE GAME just as much as calling it would be.
i'm not disagreeing with you...just using the opportunity to remind everyone the notion "refs shouldn't influence the game" is pure nonsense. whether they do or don't call something, they're influencing the outcome.
