If you have a look at the ladder the majority of teams on top of the ladder have coaches who have been at the top level for less than five years. Down the bottom you have three multi premiership coaches who are past their prime. Collingwood, Carlton and maybe less significantly essendon need to get an injection of youth in the box as well as on the field. The game has changed immesurably since the 80's and these coaches are no longer in touch with what the pace is actually like at ground level.
