Maybe all of them, maybe none of them. Pretty much all the teams in the Tavares sweepstakes - including your Leafs - are not guaranteed playoff contenders. Kings, Sharks, Blues, Sabres, Habs, Devils, Avs - whoever else is putting in an offer isn't that far ahead of us. You expect Toronto to be on this way higher tier than the Islanders, when in reality your front office seems plagued by negative rumors here and there. First Babcock and Matthews had a confrontation of some sorts. Now Matthews & Marner don't want to sign until they have to. We might be stealing your top assistant!
There's no guarantee that Toronto finishes ahead of the Islanders next season, especially considering the turmoil in Toronto contrasted with the stability brought by Lou to the Islanders. This article mentions Lou is using assets to upgrade this team, fix the holes. A core forward roster of Barzal, Lee, Bailey, Beauvillier, Eberle, with Bellows and potentially Ho-Sang fighting for spots in the lineup. So please, you go ahead predicting success and glory for your team, and doom and failure for ours.
