No so if North is not fit we will still be pretty muc full strength one player dont make a team there are 15 players on the pitch we got Byrne an accomplished international to come in at fullback and move Halfpenny to wing, so by looking at it that way losing North would be a blow but its not exactly weakening us like we have been recently with Warburton, Wyn-Jones, Jenkins, Lydiate etc being out, when a team loses one players they should be able to carry on the same when a team loses 5 or 6 players then that causes a problem as it disrupts the team.
Anyway like I said this thread is about England not wales lets not deviate away from what the purpose of this thread is for, which I do believe is people to discuss weather England are now contenders or not.
