Good teams don't look at a roster player heading for free agency and force a binary choice: 1) he's part of our core and thus long-term future, or 2) he isn't and therefore we need to maximize our asset management by trading him now while he has any value remaining.
- The Leafs are a good team with aspirations to improve this year (e.g. win a playoff round or better).
- Gardiner can help them do that.
- They likely can't afford the salary he will earn as a UFA on the open market.
- No, he's probably not in their long-term plans.
As a good team, the Leafs are about to be a club that lets players walk at the end of their UFA year. Then they sign cost-effective replacements to round out their top-heavy hi-lo mix of expensive core players and low-cost support cast. You can do this, because as a good team, you attract free agents.
In my view, the Leafs need to turn over a healthy portion of their defense to improve, anyway, to evolve into a balanced contender. So I don't see this as all bad. It just places pressure on the front office to find solid replacements.
