Not sure if unpopular but there are just too many rules. Stupid ones like ineligible man downfield. So the olinemen went 1 yard past LOS before a ball was thrown, who gives a fuck? Illegal shift or motion are stupid as well and just slow the game down.
There shouldn't be any automatic first down penalties. If the penalty yards are enough to go past a first down then the team gets first down. A 3rd and 29 defensive holding should not be an automatic 1st down especially how judgmental these types of calls are in the first place. To add to this, I hate the half the distance to the goal rules. If defense commits a penalty where the yards would end up in the endzone, put it on the 1. If an offense commits a penalty where the yards would put them back in the endzone, put it at the 1 and then add the extra yards to the first down marker (if you get off. holding on 5 yard line, go back 4 yards to the 1 and add the other 6 to the first down marker).
The nfl needs a sky judge so every flag thrown the ref that throws the flag uses his mic to call the judge to immediately look at the offending player/play and decide if its worthy of a penalty. It's impossible for refs to be perfect watching 22 guys going full speed, throw the flag and let a replay official determine if it's a good call or not.
Oh Logan Wilson got hurt that's too bad. Darn.
