This is the classic swallowing the whistle syndrome in officiating. The rules change (they are not supposed to) when it gets down to the playoffs and towards the end of the big games.
The worst sport is the NHL playoffs, they completely call the game different in the playoffs.
2nd is the NBA and then college BB to a point, but college does a little better job.
Then comes FB college and pro.
These officials have been pounded with they should not determine the outcome of a game, but if a foul or penalty occurred they have to call it, not swallow the whistle.
And when a guy steps up and makes the call they are crucified by the mental giant commentators, who don't know the rules from a hole in the ground.
Believe me hockey is the absolute worst at this, but seeing it more and more in all the sports because of the ridiculous don't determine the outcome which translates to "who cheats best at the end of the game will win"
The game is played for 60 minutes or 4 quarters etc and the game should be called the same way for the same amount of time.
