I've loved mud since mini rugby, the dirtyer i get the better i feel.... the only place i hate mud is the scrum, slipping away on the front row isnt much fun.
The new ruck law is great! Quick play, no stalling. The TMO law is okay but i'd like to see a law where each team has maybe one or two TMO requests per game. The scrum law probably won't change that much concerning collapsing scrums, the hit is only a small part of the problem and reducing it is certainly not the solution.
