Im leaning towards Lids off HB permanently. You look at other sides, they use their elite coming out of the backline. Saints Goddard, Hawks - Hodge, Bulldogs-Griff, Blues-Gibbs, Adel-Edwards/McLeod, Sydney-Malceski/Kennelly/Shaw/Matner, etc etc, all these guys are more than capable of playing midfield/wing/HF but you'll find they play a very important role coming out of defence for the majority of times. Time for Lids to go back and be our general.
Cotchin in the guts, has incredible awareness and low centre of gravity.
Polo should have a run with role in the guts or on the wing.
Tambling trade hopeless
Newman & Tuck should be helping to take the heat off the young guys
Post like all the other young guys needs to be given blocks of games to get continuity, then where warranted get dropped back to the 2's to work on deficiencies that have been picked up by coaching staff with his extended run in the firsts. Once he has worked on these deficiencies in the 2's, its back to the seniors for another extended run and so the education continues until they are AFL ready - that is how a club should go about developing its young players.
