I think the Bunker decisions take way too long, and in a close game, just sucks the life out of the game, and has people at the game, and viewers waiting a long time for the decision.
Plus they seem to nitpick every part of the tree to the nth degree, as if looking for something to take away the try. One example, was i believe a Bronocos player being denied a try, when he swung himself over the line. It wasnt double movement as the defenders for all purposes helped him over the line.
If they do get a bunker then they shouldnt take so darn long to make a decision.
I have an idea, keep the bunker. But it can only be accessed a total of six times, 3 for each team. The referee would have to make all decisions, but the Captain could challenge the call and go to the bunker.
That would make the game more free flowing, get rid of artificial breaks, stop the game from losing atmosphere, and get rid of ref howlers.
