Seems like an odd comment about Thor, he is a proven 80 minute player after last season and they have a crack at his weight and imply that he needs to be fitter to get back into the game.
I am happy how he is, let the man eat
Interestingly, if you speak to people within the Reds organization, both coaches and players, they both comment how fit Taniela actually is for a player of his build and position.
For me, his weight distribution is pretty much on point. I agree he faded a bit during the back end of games, but I don't know whether his weight/fitness are the problems with his workrate. He is still a young player, is prone to being hot headed and overexerting himself.
It's really comes down to what you want your players doing per their position. Tight head prop is one of the most physically exhausting positions on the field. Not only are you lugging around a 120kg+ frame, but you've got another 800kgs pushing against you every 5mins in the scrum. For Taniela to dominate that part of the game, and then also be making barn storming runs and big hits in defence, it's a lot to ask, even if he does strip another 10kgs.
