Weirdly enough, last year, Lammikko's DZ faceoff percentage was actually quite a bit higher than his OZ faceoff percentage. 39.4% in the OZ and 47.3% in the DZ. I think he's a bit of an anomaly, but I've noticed that it's not terribly uncommon for players to be better in the DZ, for whatever reason.
Oddly enough, the same is true for Dickinson, who had 38.8% in the OZ and 46.6% in the DZ.
There are counterexamples, though. All four main Canuck centres last year were better in the OZ, though Miller was only just barely. Beagle was 59.0% in the OZ, but 52.5% in the DZ. Sutter's difference was even more extreme at 60.6% in the OZ and 52.3% in the DZ. Perhaps most striking of all is the monstrous difference between Horvat in the OZ and DZ. He's 61.5% in the OZ, but a much lower 43.9% in the DZ. It seems like getting his stick down first is very significant for Bo.
