Actually penalties ARE reviewable...just not during game time. They are reviewed by game officials that rate the ref and justify re-hiring them. At least in High School and College.

In the Pros.....well it's anyones guess.....I've seen some pretty sucko calls.

Once back in the day....I was a head linesman....the team trailing 6-0 was on the opposing team's 5 yard line. The head ref moved up to the line on the other side of me instead of staying in the backfield...we were a three man crew .....a line plunge came up with the ball carrier's back to the head ref.....

He crosses the goal line just AFTER he is stripped of the ball. The opposing team recovers, I call time out, signal first down the other way....my counterpart (head dude) signals TD......

Little schitzengruben that was the late ball carrier yanks off his helmet and wings it at me.....

The rest was really fun...made the news....50 people arrested.
