As a leaf fan id say Johnsson is easily above Zacha on the depth chart

I agree but that Swede line would look really good I think

Johnsson can play with high end skill though. Most of his good came with Matthews

Let me help you out a bit.

Bratt-Hischer-Palmeri
Gusev-Hughes-Dadanov
Johnsson-Zacha-Boqvist
Wood-Zajac-Seney

Butcher-Severson
Murray-Subban (He is better then Carrick come on man)
Kulikov-Carrick

Crawford
Blackwood

There much better

Bratt has skill and so does boqvist plus a match up against 3rd lines they could suprise people

Not really. That second line is going to get eaten alive defensively.

That is why your first line is there. They take on the defensive role and the 2nd line provides most of the offence. Dadanov is also good defensively as well so its not just pure offence on that line.

Dadonov is both overkill and a waste at the same time

Kulikov-Walsh*
