One notable absence from his Instagram posts, however, was any sign of former teammate Mitch Marner. In past summers, Matthews and Marner were often spotted together, but with Marner now a member of the Vegas Golden Knights, their friendship will naturally take on a different rhythm.
Looking ahead, the Leafs will lean on Matthews, not just for his leadership and scoring touch, but also to help fill the void left by Marner's departure.
With a clean bill of health and a summer full of positive memories, Matthews seems poised and energized for what could be a massive season for both himself and the Leafs.
