Good defensively or not, he filled a role in that line. You don't get that kind of linestats if you don't play your part. To me he reminded of Greenway in the Wild line mentioned. While Eriksson-Ek 2-way game was probably the main reason why they dominated the goals% three years in a row Greenway did bring the corner fight potential and hard worker attitude to the line and it really worked well.They cannot have that much control. Absolutely nobody maintains an on-ice save percentage of 96%. Bergeron is a great defensive player, who has played almost exclusively in front of excellent goalies, on a team that overcounts shots against, and he has a 92.6% on-ice save percentage.
The problem is that Miles Wood just doesn't fit into this calculus of defensive sticks/rush coverage/etc. I do not think he is strong defensively.
I'm not saying it's worth paying Wood 15M like Av's did, but I do have a soft spot for hard working team 1st players that get next to no recognition.
