Huberdeau best friend and Adding another Swede

I don’t see a reason for the leafs to do that

That's so not good

Toronto does not need Hanifin and Nylander would be a horrible fit under Sutter. Also moving Hanifin is likely a big mistake, he was Calgary's best all around defenseman last year

Zadorov belongs on the bottom pairing. Move Zadorov down, Weegar to the left and Tanev and Andersson up.

Same was said about Weegar for year and years
He is a defensive Anchor and gives guys like Zadorov more time in the OZ pushing the play forward
That said the difference in ice tim in your top 4 will be so minimal you could swap Zadorov-Weegard with 2nd pair
3rd pair makes sense if you remove Stone and put in a credible LD

Someone like Joel Edmundston aka Steady Eddy
That would actually be a scary Dcore
