This is how I feel. You summed it up way better than I ever could!
The Leafs moving back into the Atlantic and against much better QofC and as a result will be in a season long battle for positioning. Whoever finishes 4th in the Atlantic will be declared the official "bubble team". Still way too early to be declaring winners and losers after we haven't reached the quarter mark.
Jack Campbell has been playing outstanding hockey lately, its the main reason the Leafs are winning and why he stands atop the goalie stats in sv% and GAA. However we also know Campbell has never started more than 25 games in a season and has his own durability and injury history and Leafs didn't sign Mrazek at $3.5 mil X 2 years to play 10-12 games a year.
Right now Leafs are getting the bounces and the goaltending and putting early points in the bank which is great.. There will also come a time when they might be ravished by Covid or have injury concerns like other teams are currently facing adversity and then we will have to see how that plays out.. Leafs have played 12 of their first 18 games at home also, which is playing an early part in the standings as its always an advantage for home teams.
PS. We all know it really doesn't matter if the Leafs finish 1st, 2nd, 3rd or 4th in the Div in the regular season, its all going to come down to being able to win a playoff round so as long as they make the playoffs that is really all that matters here. IMO
