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.

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.
