With his good two-way game, his mobility and his ability to contribute in all situations the ice would be a major upgrade for Toronto's defensive.
He would be paired with Morgan Rielly or put into the second unit with Jake McCabe which would give the Leafs a balanced and reliable top four.
At 28 years old, Walman is in his prime and carries only a $3.4 million cap hit through 2026.
He's playing big minutes and is contributing offensively with six goals and 22 assists this season, and he is also capable of handling both power-play and penalty-killing.
The proposed deal would send Nick Robertson, a 2025 second-round pick and a conditional 2026 fifth-rounder in exchange for Walman.
Nick Robertson on his side is a young player with a good offensive upside but has struggled to secure a role in Toronto since the beginning of his career.
A move to a team focused on development could be the perfect opportunity for him to reach his full potential.
While the trade would cost the Leafs some assets, the fact that they are adding a proven top-four defenseman is valued much more than the risk of losing Nick Robertson.
Acquiring Jake Walman would solidify for sure their defense and improve their playoff chances by bringing a much-needed stability at the defense.
If the opportunity is on the table then this is a move Brad Treliving should seriously consider.
