Any rebuilding team with cap space would be interested in Tavares, if Tavares will agree to waive his NMC to go there.
He’s an $11M cap hit, but will only cost you $910K in actual salary after the Leafs pay out his signing bonus for this coming season.
He’s also allegedly a good leaderbean to have around your young players. And because he’s only a one-year commitment and puts up OK counting stats, you’d almost certainly be able to flip him for a decent return at the deadline.
That said, I don’t expect the Leafs would get much of a return for him. The “return” would mainly just be dumping his cap hit. But I also don’t think the Leafs would need to cough up any real assets to get someone to take him, for the reasons stated above.
