I reckon you play Nic every day of the week. He generally comes back, plays well and then tires a few weeks later. Here we don't have that problem.It seems pretty clear that if he gets up it won't be in time to play a game or two before finals.
I'm still torn on whether we roll the dice with an underdone Nic Nat come finals. The game against the Pies really showed that we struggle to carry his reduced minutes if a runner goes down. He also tired in the last (albeit he was playing through injury) and Grundy ran amok.
If we manage to make a prelim, I think that's when you play Nic Nat. He only has to get up for two games and I doubt he'd be playing 50% game time in a final.
