I know the Leafs have to shop exclusively in the bargain bin, but this one is a little puzzling.
I'm assuming Galchenyuk must have turned them down because it makes zero sense to offer Gusev a PTO over Galchenyuk.
Gusev is a really good playmaker - better than Galchenyuk - but his skating is a serious issue and so is his size. A lot of under-sized forwards can mitigate that problem by being elusive and speedy but Gusev's skating is really bad. Because of that, his lack of size becomes a bigger issue and the worst part is, I haven't even mentioned his biggest problem: He is atrocious defensively.
I don't envision a scenario where Gusev could crack this roster, but that being said this coaching staff has made some puzzling choices before. After seeing Sheldon Keefe repeatedly put Joe Thornton out on the first line and on the first power play unit - including doing this in must-win playoff games - I really don't know what to expect from him.
The Leafs obviously have nothing to lose here, but the defensive issues and poor skating are really problematic. I suspect the thinking here is that Gusev could be paired with Tavares who's skating wouldn't leave Gusev in the dust and Gusev's playmaking abilities would be complimented by Tavares goal scoring ability but you would need to have a physical winger to put on that line who is absolutely rock solid defensively to give that line any chance and the Leafs don't have that piece.
