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.

Mitch Marner explains the two key reasons behind his decision to leave Toronto and join the Golden Knights, just hours after finalizing a sign-and-trade worth $96 million.

Perhaps the biggest pending free agent is already off the market. After a sign-and-trade with the Vegas Golden Knights, star forward Mitch Marner signed an eight-year deal worth $96 million, so he'll be in the desert for the foreseeable future. In return, the Maple Leafs got third-line center Nicolas Roy.
