1) Leafs - Since the only real downgrade the Leafs had from last year was losing Kapanen, but we added a major upgrade in Brodie and improved our depth, we should easily be #1. Main concern is Andersen, but if he holds up and there are no injuries/major struggles from top players, we should be up there.
2) Jets - This one was a bit of a toss up for me, but the Jets have the next best overall team. Like the Leafs, it mostly comes down to performing. They did not get worse, but they did not get much better either (Eakin to Stastny being their main move).
3) Flames - I think adding Markstrom will be huge for them. Goaltending has been a major question mark for years and now they have two quality goalies in Markstrom and Rittich. They did lose their defensive depth, but it is still a pretty solid defense and their forward group is more or less the same. IDK if they have enough to be #1, but #2 or #3 should be the expectation IMO.
4) Canucks - This one is a toss up between the Oilers and Canucks. The Canucks roster lost a couple of key guys and did not really add anything except a Markstrom replacement. I think they regress, and outside of getting a hot goalie performance in the playoffs, they did not do all that well in the first place. Also have the worst record against Canadian teams in recent history.
5) Oilers - They could go as high as #2, but their goaltending still sucks, their defense is still pretty bad (and that is with Klefbom), they still lack depth all over the place, and it will still mostly come down to McDavid and Draisaitl. McDavid and Drasaitl will have to carry them, and can carry them far, but all of the teams above them have good core players themselves and have much better depth and goaltending.
6) Habs - Great wing group, solid defense, good goaltending, but the lack of center depth is going to kill them and they lack any kind of game-breaking talent. They could make the playoffs, but in general, I think they will be just outside of the pack at the end of things.
7) Sens - Should be really good in a few years, could make some noise, but generally they probably even expect to be last place again this year.
The Leafs are set up on paper to make it to the Final 4. It's up to the top guys (Marner and Andersen especially, given they underperformed last year) to make that happen, and for the depth guys to fall in line behind them. We are the best team in this Canadian Division, so the focus is squarely on the coaching and definitely the players to make it happen.
