But I suspect the NRL will not have the balls to do away with the two ref system and admit they got it wrong.
They've effectively set up a "career pathway" for refereees... touchie, to joint ref, to senior joint ref, to video ref. When there was two touchies for every one ref, career progression was stagnant, but now every touchie can see themselves a chance of eventually becoming a refereee.
Of course we could debate the decline in quality of refereeing, given they have reduced the benchmark to gain a top grade appointment... which (bringing this thread back to serious off-footy topics) is kind of like the debate about the supply and demand entrance ranks for different University courses.
