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.

Nicolas Roy is a solid third-line center who will help the Leafs and represents maybe the best-ever return in a sign-and-trade deal.

Toronto Maple Leafs general manager Brad Treliving heaped praise on Mitch Marner after the trade to the Vegas Golden Knights went down.
