Gaunce hasn't looked all that good in AHL. He's running around a lot in the defensive zone and isn't particularly mobile. I'd be very surprised to see him in NHL this year unless we have tonnes of injuries.
I would still give Gaunce a try. Let`s give him 10 games and see how he does. Same for Barrie.
I would like to see Elliot play all season, I know he is super soft, but at least he can pass the puck and his wrist shot would really help on the power play.
