Gaunce is a bit of an in-betweener as a prospect. He has the size and body type of a power forward but doesn't play a combative style. He has been able to put points up at the junior level when surrounded by talented players, and has a big shot, but he is not a pure scorer and his skating and technical skills are not considered elite. To succeed at the pro level he will need to pay keen attention to the defensive zone and win most of the puck battles along the boards and in small spaces. He has shown some promise in his first pro season but is still a project at this point.
