Agreed. He's taking also taking tougher draws this year than last year......and he's holding his own.
Like I said before, statistically, the difference between him and Bergeron is about 1 faceoff win per game.
Your math isn't quite right here. The top guys take about 20 draws a game. Coyle at 50% wins 10 of those, Bergeron lands 12. So roughly 2 more per game. Which still doesn't sound like a lot, but having 10% more starting possession over the course of a season can have quite a big impact. That said, Bergeron was elite of the elite in this regard, and I always think that as long as you're tracking at 50% or above, you're doing just fine. Coyle is hitting that mark, so no major issues there.
The more important aspect I think is the ability to win those clutch draws in high pressure/high need situations. The ones where you need to win the puck late in a game to try and equalize or protect a lead, or to get first use on a critical PP. Especially in playoffs. Bergy always prided himself on winning a lot of those, and it was one of the signs that he was just fading a bit last year that he was starting to lose a few more of those key faceoffs. It was something he himself spoke of as being frustrating, even though his raw numbers never dipped.
Can Coyle be trusted and deemed reliable in those same situations? The evidence so far is pretty patchy. As usual, the postseason will be the ultimate and determining test. Hopefully Charlie can step up in that regard. Don't think it's a big deal, but it does matter.
