Not as though he is keeping kids out of games atm and it would be a similar scenario next year.
Dion or Ross, Dow McIntosh in the mid field.
Midfield group next year
Taranto, Hopper, Prestia. there's your experience. Still developing Lalor, Smillie, Hotton, McAuliffe, plus two first rounders. The first 7 we hope is our core group next year and the first rounders get games.
Thats just a total of 9 mids we need to get it closer to 14 or so for development and depth in the seconds.
If seven mids is a standard each week and with the bench that is pretty normal for most teams, then the easy way to work out how many you need is simply mirroring as best as possible the number in the seconds.
Even if you include the likes of Sonsie Ross and Dow there is still a need for more.
With all that above can see no reason why Prestia could not go around again.
