Roger,
I have considered that of course but I cannot see that we are on the right track when we are getting the fundamentals wrong.
If, we were playing 2 talls forward (of any variety just now) and rotating marking players from the midfield going forward as you would expect and we were losing games, you'd be right in saying that we are doing things right and just need the players to develop. But instead, we are playing a reduced forward line, not practicing effective forward entry tactics, not practicing precise kicking, not practicing leading patterns....in short not doing any of the things we need to be doing to develop those players.
It seems to be a case of wait till they get to 50 games and hey presto, like magic they will suddenly start doing all the things we haven't practiced. Thats why I'm not seeing signs of incipient premiership material
