Marner seemed OK with all of that in the early days of his Leafs career. He earned rave reviews from the Boston Bruins after his second playoff series in 2018, when he shined with nine points in a seven-game loss. He piled up 94 points, the most by a Leaf in more than 20 years, as a 21-year-old a season later.

Marner's outburst attracted criticism, but Maple Leafs coach Craig Berube gave some context to the controversial reaction. Speaking to reporters after the 6-1 loss, the Leafs coach said Marner was trying to light a fire in his underperforming teammates.

As soon as the final horn sounded after the Toronto Maple Leafs' 6-1 loss to the Florida Panthers in Game 7 of their second-round series, Mitch Marner was the very last player to leave the ice. He looked like a player who may have played his last game with the club.
