Your mids and probably your running h/b are the ones your looking to rotate and rest the most.
Last year we used in most games at least or to put it a better way went into most games with 9 mids 10 if you include big Toby who also needs to be rotated a lot.
In what world is Cotchin not one of our best 9 mids? .I really dont think that is debateable. What needs to be sorted is how we use cotchin as a mid and how much game time he is given.
Last years prime list of mids with the games they played
Prestia 19, Nankervis 23, Baker 23, Short 23, Graham 20, Bolton 23, Ross 15 and of course Cotchin 19.
Then we had for limited games Martin 9 and Sonsie 7 the latter should have played a heap more imo.
Of this group Cotchin continues to be a better mid than Graham, Ross, Short, Baker, and imo Martin given his last couple of seasons and young Sonsie but that can change quickly with this kid.
Then we had wingers Pickett 19, McIntosh 21 and Ralphsmith 13.
Positional players out side of mids.
Backs
Vlastuin Broad, Grimes, Balta, D Rioli, Tarrant. They are getting picked no matter what. Atm it seems Baker is the outlet or 7th defender.
Forwards
Riewoldt, Lynch, Two of Cumberland, M Rioli, Clarke, one of Miller or Ryan.
That leaves 11 spots for potentially all mids including wings and ruck.
Mids in order.
Wings - McIntosh, Pickett. Atm they are probably locks Ralphsmith is a possibility.
Ruck - Nankervis. Only question is who will partner him hopefully one of Miller or Ryan as fwd/rucks..
Mids - Taranto, Hopper, Prestia, Bolton, Cotchin, Martin, Sonsie, Sub Graham. Ross, Short last two as emergency.
When there is a better mid option than Cotchin then maybe we can talk about him not being best 23.Until then we can talk about his game time and what roles he should or should not be doing outside of his mid role.
