As much as I hate penalty plagued games, I have to wonder that maybe it wasn't them. Maybe the calls were all good calls and they have good eyes?
The reason I bring this up is I'm thinking back to I believe the Ram's game when all the o-linemen were complaining they were being held and it wasn't called once. Maybe a crew like these prevents BS like that from happening because they aren't afraid to call 3 penalties in a row to get the game clean.
And this game did clean up in the 2nd half as the teams had to adjust and stop doing stupid and/or illegal things. Just a thought.
