Think Carlton is still a fair way off with natural progression. Mostly it was the old blokes who carried the side on Sunday. By the time the young brigade (i.e. younger then Cripps) are quality players, the old blokes will be done. They have a cavernous list gap between 23-28yo. Of course the development process could be accelerated with brown paper bags.
North is in no man's land as a mature team that didn't respond and got their coach sacked. Shaw is going to need to get more out of the same blokes, while tapping some veterans on the shoulder and developing youth. No quick fixes that I can see.
Both tough jobs, but Shaw's is tougher.
