The problem is usually the call is technically correct but not called very often so coaches, players, fans get consditioned a certain way. I mean, I am habituated to seeing guys lining up offensively and defensively past the LOS and it’s not flagged. Defensive guys coming across early is maybe a 50/50 chance of a call, at best.
I remember when the scab officials came in during what 2012 (?) and in many cases started calling games by the book on things like holding and interference and coaches, players, fans went absolutely apeshit. They wanted the “old” way where they “let them play” (until they don’t, on a random basis - or not so random maybe).
