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.

Marner was set to hit unrestricted free agency for the first time in his career after his contract with the Maple Leafs expired on June 30. Rather than hit the open market, he was dealt to Vegas in exchange for Nic Roy and proceeded to sign an eight-year contract worth $12 million per season.

Mitch Marner will be an unrestricted free agent on July 1. But the Maple Leafs appear to be ready to take action if he quickly signs with the Golden Knights.
