I actually prefer Toronto’s group by a fair amount over Edmonton. But I’d rank Toronto above average. Maybe 12th to 15th. The age of some of them is the biggest concern.
I have them both in the exact same tier pretty much. Funny enough right in that ~13-16 range
Colorado
Carolina
Boston
Calgary
Nashville
That's my clear Top 5. Order is fairly debatable outside of Colorado at #1, but those 5 teams pretty much all have that combination of a very deep Defense and an elite #1. Calgary the only ones without an elite #1, but basically 3 Top pairing quality guys and I would argue 5 guys that are easily Top 4 quality. After that I'd have a group of 4 in the next tier down, Tampa Bay, NYR, Washington, and Minnesota.
Then honestly I'd have a pretty gigantic tier of Defense's that are fairly close to one another where I think arguments could be made either way. That group would include Edmonton, Toronto, LA, Florida, Vegas, NYI, Dallas, and Pittsbugh. But personally both Edmonton and Toronto fall pretty well in the middle of that group.
What's interesting is IMO Toronto doesn't have much room for growth defensively this year(I dont think Sandin or Lilijegren take any sort of step forward, especially not with both dealing with different issues early in the year already), and with some older guys on that Defense they're primed for further regression from the likes of Gio/Muzzin/Brodie.
