Tanev and the Leafs have been linked to one another for several seasons running. After splitting last year between the Calgary Flames and Dallas Stars, it would appear as though Tanev is finally coming home.
Tanev, 34, is a pure defensive defenseman, who isn't going to contribute much on offense. He will, however, be a strong addition to the team's struggling penalty kill and brings a ton of experience and intangibles to the table for the Leafs.
Rumour has it that the Maple Leafs may be ready to offer more term than other teams, knowing full well that the final year or two of the deal may end up being paid out to Tanev via an LTIR retirement, AKA "Robidas Island".
