Faceoffs matter drastically less than shot attempts shortly following a faceoff. In short, if a team gains clean enough possession to generate a shot attempt in the seconds following a faceoff, it was a meaningful faceoff. If the face off just ends in a battle between two wingers for the puck in the corner, it wasn’t particularly meaningful.
Team play also has more impact on faceoff win% than many like to realize. The center is credited with winning or losing the draw, but often time it’s the play of the wingers and D winning a battle for a 50/50 puck cleanly that ends up determining who actually won. Both the skill of these players and the strategies implemented by their coaching staff can impact faceoff win% of the centers.
Tyler Dellow had an exceptional article on this topic several years back. He showed how the Oilers made a change that increased their faceoff win%, but actually ended up giving up more shots against following faceoffs, and how that impacted their season performance. Unfortunately that article was deleted from his blog when the Oilers hired him to do analytics work.
Puckbase (formerly faceoffs.net) does still track post faceoff possession metrics. Each of Eller, Backstrom, and Kuznetsov have positive net shots post faceoff, and Eller is ranked quite highly. Kuzy’s stats are actually being propped up by really good D zone numbers (his neutral zone is exactly even and his offensive zone is negative), but he’s only taken 19 d zone draws this season so that’s still pretty noisy and not particularly reliable.
