You could almost hear Gary Bettman's teeth grinding as he faced the microphones.
Donald Fehr is getting to him.
Among other things, Bettman accused the NHLPA excecutive director of "spinning us all into an emotional frenzy."
He added that the NHLPA's "shockingly silent" response to the league's latest and most generous offer left team owners "beside themselves."
Fehr's bob-and-weave tactics - we're never sure exactly what the PA is up to - are also frustrating to fans and an exhausted media herd.
But so far, it's gotten results.
Throughout this lockout, Bettman and the NHL owners have tried to insist that their latest proposal is the limit. They won't give another inch.
But the offers have been getting better.
This week's revised offer included concessions that were supposedly impossible a couple of weeks ago.
Fehr and the players apparently believe they can do better still, once they wait out all the abuse hurled their way.
Keep in mind that the NHLPA has been on the back foot throughout this process.
Whenever and however the lockout ends, the players will be left with less than they had before.
Fehr's job is to minimize the damage.
Though it's not without risks - media reports suggest heated discussions and disagreements within the NHLPA membership - the Fehr method has managed to nudge the players' agenda forward.
