I think, if Cuningham is fit enough to play for the NB's then he's fit enough to play ones.
He looks a far better player than Polson at this stage and should take his place. FFS Polson played 61% of game time last week, surely Cuningham can do that.
Just as much chance to be injured in the twos as there is in the firsts.
Debate Kennedy v Cuners, as I have already stated Polson should do a stint in the VFL
