Quoting: ChiHawk
Well I won't agree that Toronto was last year or is a very good defensive team this year. They are average defensively. They have a couple great defenders but some big holes defensively. Andersen was put in tough situations because of it in Toronto. Mrazek only played 2 games but he's not going to look much better and not better then he did in Carolina. Carolina is head and shoulders better then the Leafs defense the last couple years and had nothing to do with Mrazek.
again, they are literally top 5 in the league by the defensive metrics and have been for the past two seasons, and if Mrazek gets healthy he will look as good as he did in carolina when he was healthy, which is a good 1B.
As far as Carolina being heads and shoulders above the leafs defensivly, currently this season
Leafs 1st in CF, 6th CF%, 1st FF,11th FF%, 8th xGA, HDCF% 9th
Carolina 18th CF, 2nd CF%, 18th FF, 3rd FF% 21st xGA,, HDCF% 8th
Carolina is better, but the gap is not very significant
