BOSTON — The Celtics made playoff history in Game 1 on Monday night while blowing a 20-point third quarter lead to the underdog Knicks. The hosts shot just 25 percent from the field from 3-point range in the 108-105 overtime defeat, going just 15-of-60 from beyond the arc.

The Celtics didn't -- and for the most part don't -- have a plan B. Jayson Tatum was freezing cold down the stretch and just kept doubling his bet thinking one would pay off. It never happened. He finished a paltry 4-of-15 from 3 and missed all five of his fourth-quarter triples.
