If Gaunce were a better skater, he would be considered top-6 material. As it stands, his attention to the defensive side of the game and ability on face-offs makes him a definite candidate for role as a third-line checking center. Gaunce has the size to battle with most players but doesn't always have the speed to keep up. But he'll pay attention to the defensive zone and win most of the puck battles along the boards, making him a potentially valuable player when a team is looking to preserve a lead.
After a very strong Team Canada World Juniors Summer Evaluation Camp, Gaunce will look to keep momentum now that he has management's attention. While earning a spot with the Canucks out of training camp is possible, his coaches will be careful to not rush him, giving him more time with the Bulls in Belleville to fine-tune his game. An effective two-way player, with leadership upside, Gaunce has the inside track as a checking line center and penalty killing specialist. As his offensive game is beginning to flourish, his ceiling could grow higher.
