I don't know what it is about Avs centers but I swear their situational faceoff win % takes a major hit the moment they don the uniform. Bellemare was great until he was in Colorado, Kadri wasn't as effective IIRC in Colorado as he was in Toronto, and Eller took a nosedive as well. I'm guessing J.T. Compher will turn into goddamn Paul Gaustad wherever he ends up.
And of course they signed Jesse Winchester for faceoff help, and he died in the preseason.
Glendening I'm not opposed to but watch what happens if they get him. He'll be the next Alex Newhook/Tyson Jost in the dot.
Conor McGahey once said during an Avs broadcast that "Even when the Avs win faceoffs, they lose them." There is something to that--it's like the puck support right after a faceoff just isn't there. Some coaches want their wings to collapse on the puck right away or move closer to the puck at least. I don't get that impression with Bednar's system, but I think that's a reason why the Avs suck so bad at faceoffs. They just don't GAF about them that much.
As for Engvall, I'd LOVE to get a guy like that, but I don't think they'll be able to afford him.
