NHL free agency has arrived, and that means teams around the league will be looking to make upgrades to their rosters for the 2025-26 season. Many teams have already taken care of business before July 1 by re-signing key players to extensions.

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.

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.
