That 2nd line isn't gonna produce enough to compete with other teams. Only chance is the depth

Its not the strongest 2nd line in the league but its a massive improvement from last year. The top line carried the Avs to a top 10 offence in the league with no depth at all. Now with a passable 2nd line and a strong 3rd and 4th line the offence should be even better

I think its fine, Kadri will have a much better production in his true 2c role vs 3c last year. Plus the chemistry he has shown with Jost and Donskoi already, I think that line will suprise you (I am not sold Bura stays on that line)

Neito will be either 4th line or possible the 13th forward. Wilson will be line 3 and val,vlad, and neito have to fight to be line 4. One will be line 4 one will be 13th forward if any Injury and one will be scratched

I think they'll be fine. I don't expect them to put up 50 points each, but the Avs don't need them to. Jost looked good in the playoffs last year, Kadri is the definition of a great second line centre, so I think it hinges on Burakovsky. Personally I'd have Donskoi there, but we'll see. My favourite alternative would be moving Rantanen to the second line with Jost and Kadri. I absolutely believe Rantanen could drive that second line.

Landeskog - MacKinnon - Donskoi
Jost - Kadri - Rantanen
Wilson - Compher - Burakovsky
Nieto - Bellemare - Calvert

That would be my choice.

If they split up the top line I personally like the combos of

Jost Mack Rants
Landy Kadri Donskoi

the thought of a Landy Kadri pair would be a nightmare for other teams being shut down constantly. Jost with Mack can help with some additional C support, like how Landy does with Mack taking draws
