North have been trapped in the middle of the table most of the time for many years which means your not all that good or all that bad and dont get good draft picks unless you have something to trade, so never have any real sustained improvement. They have occassionaly made some limited impact in finals but never getting close to a GF or flag. So unless you have a crap season like they have so far and finish bottom 2 they wont get the good picks which in most cases lead to significant improvement ............ unless your Carlton of course. 9++ years for a coach is a long gig without any real success so they need to findan experienced coach with some presence like a Longmire, but he would be leaving a re-building programme to go to another re-building programme.
