Mitch Marner trade rumors that dominated headlines earlier this summer, with Utah Hockey Club being one of the teams reportedly interested in the Leafs winger. That being said, Keller and Matthews are buddies that go way back. Both played for the USNTDP prior to getting drafted to the NHL. They also were teammates several times, representing the United States at multiple World Junior Championships.

Granted, it would be pretty awesome to see Matthews and Keller play for the same team in the NHL, but that would likely only ever happen if Keller somehow made his way to Toronto.
