The thing is that in key moments, especially playoffs, JEE(and others) are not going against just any FO guy, but the best that the other team can put out there. Those FO %'s are against the average FO guy in the league. If he went against an elite FO guy his numbers would be more like 40%.
When you win a FO on special teams it's a big deal. Means a clear for the PK, and control of the puck for the PP. In final moments of big games, i.e. when the goalie is pulled, it's an even bigger deal. I don't think it's a coincidence that FLA won the Cup with Barkov winning over 57% of his FO's.
The FO's in the neutral zone and at 5 v 5 are less important. A smart coach knows this - Lemaire sure as hell knew the difference as he was a Center playing under Bowman who always had at least one C who was terrific on draws.
I don't disagree with any of this, but that's not really the same as "he needs to go from 49.7% to 51% to be considered good". Comparing what he did last year to what McDavid did, the difference there is negligible.
Like I said, that's 21 additional wins over the season. Maybe five neutral zone, eight offensive, eight defensive, the chances any of those would have led directly to goals for or against is real low too. It's just not a meaningful difference there.
Going from 49.7 to 57? That's a bigger difference. That's 117 more faceoff wins.
It was never a post about how faceoffs don't matter at all or that he shouldn't try to improve. It was specifically the idea that 49.7 is bad and McDavid's 51 is notably better, and harping on the difference between those two figures is overrated.
I also took exception to the idea that 21 faceoffs leads to 21 more minutes of possession because, even if we don't have real numbers for what those faceoffs translate too, it's pretty unreasonable to expect it to lead to 21 minutes of possession, and that shouldn't be a controversial thing to say.
