I think the point is that we need to have clear targets for the managers who train for the NT. If we set the policy that bigs need to have decent passing, and that we don't care as much if the Inside D is above 13, then that is what the trainers will train. We all have to be on the same page. NT managers can't just cross their fingers and hope. Now, I'm not saying that's what you are doing, and I understand that you can only do the best with what you are dealt.
However, since the England team is out of any serious international contention, now might be a good time to take stock of what we have and get everyone on the same page. Encouraging us to train big men with horrible secondaries and HoF potential is a waste of time because in 2 years, when they are half decent, the current crop of 23 year olds will be much better and that HoF player won't even make the NT.
