Reading through his dad's Wiki..
"Carrying a reputation as too slow a skater to succeed in the NHL, Perreault played three years for the St. John's Maple Leafs, Toronto's American Hockey League affiliate. Perreault led the St. John's Maple Leafs to a seventh game in the Calder Cup finals in the 1992 season and to first-place finishes the following two seasons; his 132 goals and 276 points became in that span, and remain, career records for the Leafs' American Hockey League franchise.
Perreault made his NHL debut in that third season with the Leafs, showing some flash in spot duty, before being traded to the Los Angeles Kings for a fourth round pick in 1994. He spent most of that season with the Kings' minor league affiliate, the Phoenix Roadrunners, scoring 51 goals to lead the team."
They're more or less the same size - 5'11, Gabe is listed at 165 right now on Elite Prospects, Yanic is listed at 185 on Wiki. Gabe can become as good at faceoffs as his dad was.
