I think thats where the team element comes in, they should be a coherent unit.
I also think, providing they stick to the rules, consistency shouldnt be hard to find.
And, for me, it should be broadcast - like Rugby. Im convinced if you can hear conversations pretty well all controversy will disappear.
Ref 1: Was that a pen?
Ref 2: Yes, give it.
Ref 1: The ball is in the net, I cant tell if thats offside
Ref 2: He is being played on by the LB, its good.
Ref 2: Theres something happening in the box when that free kick was taken, give me a sec
Ref 1: What happened?
Ref 2: Harry Kane just got done by a piledriver tombstone, penalty to England
Its really not like there needs to be an argument, or even seniority, is it?
