"When I was younger I didn't really get what they meant by that, so I didn't really know what to think. I just played hockey," Marner said. "But when you're growing up and you get told that, you get a little fire in your stomach. You know when you're playing against that team, or know when that person's watching you."
But Marner's parents, Paul and Bonnie, made sure their son didn't let that negativity have too big an impact on him.
"No matter who said that about me, my parents were always there behind me," he said. "My family always made me feel I was always the biggest person on the ice."
In many ways, no matter what height and weight he's listed at, Marner's other skills do make him seem like the biggest player on the ice.
"That stuff tends to be overrated, the size stuff, especially for him," Marner's linemate James van Riemsdyk said. "He's smart, he uses his edges, he's got good balance, he knows how to position himself on the ice to get that leverage and body position on guys. The strength thing comes into play maybe when it's two guys stopped, standing on the wall trying to push each other off the puck. But other than that, it's a moving game. You're trying to use your momentum and use your edges and try to get yourself in and out of certain positions. He's shown he's got a good knack for that already and that size becomes less of a factor."
A perfect example of that came against the Florida Panthers at Air Canada Centre on Thursday.
One of the 17 players this season who had an official hit on Marner was Panthers defenseman Mike Matheson at the 5:04 mark of the first period. Just under 12 minutes later, Matheson was riding Marner's back while he came in on Panthers goalie James Reimer, and scored a highlight-reel goal by displaying his tremendous edge work on his skates and his quick hands.
"It's not how big you are, it's how big you play and how competitive you are," Maple Leafs coach Mike Babcock said. "Obviously the hockey sense goes a long way with that, edges, all those things.
"He looks like a hockey player to me."
