Gunnarsson's been getting his name dragged through the mud for the first four games this season pretty much non-stop when he hasn't even been that bad. He and Phaneuf have been keeping their opposing lines in check all four games now.
Plekanec line, Giroux line, Spezza line, Duchene line have all been held pointless and while a lot of it has to do with how good Phaneuf has been, Gunnarsson has been doing his job as well. Though he did have a rough last game.
Kulemin is not underrated around here but to the general casual Leaf fanbase and outside, he is.
Anyways, I'm saying Gunnar because of how everyone is already talking about him this season.
