Saw a little article in the paper today, just thought I'd share it. According to Dater, Roy said he is leaning towards lines of:
O'Reilly - Duchene - Parenteau
Landeskog - Stastny - Tanguay
McGinn - MacKinnon - Downie
With that said, I would guess the 4th line to be:
McCleod - Mitchell - Bordeleau
Looking at these top 3 lines, the Avs look to have a pretty good offensive input whenever these guys are playing. This team still needs a serious defensive boost, but as of right now the forwards look pretty solid.
