I would not argue playing him in the first team every week.
I would not argue putting him in the front row because he is big.
But London he could have done 40 - 60 minutes against big fella's. Gets his fitness up and if it looked like he was struggling there was plenty on the bench to cover for him.
It's a fine line to be sure, but Leeds was a tough game to get thrown into and it has raised questions of if he can do 2 ten minute spells against the best, then he could be very effective against the lesser sides than Leeds.
