This is a confusing situation that apparently involved the permission from the Maple Leafs that allowed Kyle Dubas to speak with the Avalanche later being revoked.
From Friedman on The Fan 960:
This is a weird story. There have been a lot of twists and turns here. First of all, I think it’s over. That whatever window was there since I reported it… one of the things I said on Tuesday when I mentioned it is I’m not exactly sure when it [was]. Sometimes when you actually go to air with something or write something it brings even more clarity, and that’s the case here.
