Not gonna take a guy seriously when he places Edmonton and Toronto in the contender category and St. Louis in the playoff category. He seriously doesn't know what he is talking about.
I think there's some optimism for Canadian teams in his content for sure.
You clearly didn't read the title, let alone watch the video intro - this clip you're referring to is about the expectations of the public regarding teams and what their seasons should look like, it's not a ranking based on his opinions.
I trust someone who watches a large portion of the televised games, and makes his livelihood off following hockey related news to characterize teams better than a staunch one team fan.
TOR pushed Tampa to a game 7 OT - Toronto got worse in net, but much like Colorado has explosive forwards and a great transition game. They're going to finish with 110+ pts this season, are poised to be media darlings - how else do you characterize that team? Truth be told, they're the pre-2018 Capitals, all the talent with no success where it matters. I don't see Murray as an upgrade on Campbell in net and believe WSH jettisoned Samsonov for a reason - TOR is going to take a step back this year, solely based on the goaltending.
EDM dazzles with the face of the league and a flashy offence. With reliable goaltending, they're going to finish with 105+ pts this season, a pair of 110+ pt forwards and a top 10 GF ranking with innumerable highlight reel plays. Again, the public perception is they'll outscore their flaws in the playoffs - they're capable of challenging anyone etc etc...
Of course, I hate hearing all about it on Canadian sports coverage - but it's exactly the opinion of the general public, especially north of the 49th parallel. The Leafs COULD go on a run. The Oilers WILL go on a run.
This ignores that champions shut down the opposition in the playoffs, they don't outscore them playing run and gun to hoist the cup. I don't expect to see Edmonton or Toronto make a trip to the finals anytime soon, but I do think that we'll see one or both of them in the 2nd round come spring. Depending on the matchup, I can see Edmonton making another conference final - because that Pacific bracket is soft in comparison to the Central and Metro ones.
