NHL Central Scouting’s Peter Sullivan
"Gabriel does remind me of former Kitchener Ranger (and Philadelphia Flyers captain) Mike Richards. He sticks up for his teammates and is as strong at both ends of the rink as any player in the draft this year. He competes as hard if not harder than anybody. He's got all the assets that you need to be a team leader and, for a potential No. 1 overall, that's what you would want."
NHL Central Scouting's Chris Edwards
“He is a good-size guy who is solid on his skates, not afraid to take the puck to the net or battle for it along the boards. His skating is very good in all areas. He plays the game with so much passion, he plays the game hard, he's a great mentor for players that are younger and older, maturity beyond his years. (He) doesn't need one game in the American league next year -- he should step right into the NHL. I think the team that gets him next year is going to get a player that helps them win a Stanley Cup.”
