This. The Avs are so caught up in their assignments that they will just leave a guy with a wide open lane to the net, f it's not that player's assignment. It is so strange. I don't know if I like Man to Man. It hardly ever leads to situations were we outnumber the opposition in puck battles, which leads to spending so much time in our own zone. On paper it means should never be open, but as soon as one guy gets loose we are left in a bad situation.
I think it would work if the majority of the Avs could win one on one battles along the boards and in the races to retrieve the puck, but as a whole, they haven't shown much of that yet (especially the defensemen).
