Here's another write up from the Dallas hockey blog, Defending Big D:
I hadn't looked at him in too much depth prior to the draft, so wasn't sure about how good a pick he'd be for us. What I think after having had a look at some of the scouting reports is he's a more complete/all-around version of Joseph Labate, or Kesler without as much skating ability/speed.
Labate's taller, and may be more dependent on his skill to become a success at the NHL level, while Gaunce could fall back on his defensive play and intangibles to be successful at a lesser role. Both are in competition for a 2nd/3rd line center role based on their potential, and Shroeder will have to fit in there somewhere too unless his offensive game improves.
Gaunce has already filled out his frame pretty well considering he's a year younger than Labate and they might just be challenging for the same spot at the same time in the next couple of years.
Gaunce seems like he'll end up have a similar development path to Kesler, but plays a less chirpy game so he'll be more focused on playing responsibly rather than trying to get others off their game. He doesn't have Kesler's skating, but seems to be in the right areas for turnovers due to his hockey sense, and could match Kesler's ability as a responsible, two-way forward initially for us.
It'll be interesting to watch him more closely now that he's in our system.
