On the subject of LMS, I don't think he is match fit.
He appeared to be physically struggling at various times in the game.
I suspect he is putting his hand up to play when not really match fit.
His stats show a significant drop off in metres made from the Wigan game
In addition when comparing his volume of tackling. This is significantly less this year than in previous years.
There is also the argument that Brown came into the side in 2013, and the way Brown plays the forwards isn't suiting LMS.
