The Leafs drafted Marner with the No. 4 overall pick in the 2014 NHL draft. If Marner, who scored a career-high 102 points this season, doesn't return to Toronto and leaves in free agency, he'd do so having racked up 741 points in 657 regular-season games with Toronto, along with 63 points in 70 playoff matches.

Mitch Marner could become an unrestricted free agent this summer, and there figure to be plenty of teams interested in acquiring his services.

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.
