The real conspiracy is that a lot of eyeballs are watching the leafs so refs will call the game as accurately and fair as possible. Which means it's unlikely leafs will get any favors especially since they're not a rough team. (And yes, in the moment of a game, refs essentially do give favors due to whatever they feel like the flow of the game should be like) Leafs definitely do once in a while (peculiarly this season) but it's usually tilted towards the other team because they know how to play agasint the Leafs and everyone knows refs won't call everything. Plus they don't want to look bias (Darryl Sutter call out). Hence why Leafs play one of the most 5 on 5 hockey. They've have been at the bottom half of the league in Power play Opportunities and Penalty Kills for a while now.
Though I'll say again, this year is a bit different. Maybe Darryl Sutter is actually onto something
