I know every penalty can't be up for review. The truth is, most of them are subjective. Was it pass interference? Was it not? Was it on the defense? How about the offense? But should a straight forward penalty like the face mask be reviewable? I was just watching the Ohio State vs Michigan game and the UM player grabbed the OSU player's face mask on a punt return and twisted his head back the opposite way and no official saw it to throw a flag. I hate face mask penalties and I think players should be called on these every time. They want to talk about player safety but then they leave stuff like this up to the eyes of the officials.
