Keep your pants on Enforcer, no one is saying he is going to dominate the opposition, they are purely replyng to the remarks that 7 will be a weak position in the Reds lineup..
As for the physique, I think it's obvious to anyone who has seen him over the past 18months, albeit it sevens, schoolboys or club rugby that he has bulked up... As for his been ripped and not big, yes that could be the case, but fortunately for us there are plenty of photos where he is standing next to 90-110kg guys, so it gives a basis for comparison..
