The NRL actually said that they would alter the way contract values would be applied. It hasn't happened, but they were saying that no club would get away with offering unders and topping up an offer with TPA's. But it would directly cause grief for their four glory clubs so it's only been lip service.
As far as it goes the fact that a few clubs can supposedly pay unders has caused a situation where clubs like the Titans have had to gamble on potential with big money offers. We took a similar gamble on Mbye to the Titans gamble on Taylor.
I get a bit closer to switching off from this crooked competition every year. Losing fans is a bridge that the NRL can't afford to burn. But the current heads of the game just don't give a crap.
