The Toronto Maple Leafs signed and traded star right winger Mitch Marner to the Vegas Golden Knights Monday, ending the 100-point player's stint with the team and leaving a massive hole at a key position on the offensive side of the puck.

With many of the NHL's potential free agents re-signing with their old teams, Leafs GM Treliving shows restraint.

The move was an emotional one for the two-time All-Star, as Toronto was the only team he had ever played for since being selected by the Maple Leafs with the No. 4 pick in the 2015 NHL draft. On Tuesday, Marner penned an emotional farewell letter to Toronto fans in which he said not bringing them a Stanley Cup was hard on him.
