Refs made a couple really, REALLY bad calls this game.
Trouble is, the Celtics know this.
That's a problem because other than some REALLY bad calls, there have been tonnes of on-the-line calls. Or calls the refs got right but they looked bad, or they were borderline the right call, etc.
Those now all seem like crap calls too. Because they had those crap calls.
Super terrible refs, but still not as bad as the Celtics are currently thinking.
They need to get over it and play their game. Currently, we're beating ourselves by taking rubbish shots.
