Having 3 officials gives you one more "show" to deal with in an AR or linesman. These people like to talk to the parents/coaches more than the middle official does. They don't talk to the players because that's specifically outlined not to be done. Why in god's name do they have to talk to parents and coaches on the sideline? By talk I mean things like "AHHH YES HE WAS OFFSIDES!" or "COACH SIT DOWN IN YOUR TECHNICAL AREA! I WON'T TELL YOU AGAIN!" (what area?).
It also is cause for a law suit because it would be an extra official especially close to a Chuck Norris roundhouse kick. We all know they could never escape this. They weigh 300 lbs on average!
