The Celtics entered this week with a 46-1 record this season when leading by 16 or more points.
Make that 46-3 now.
For the second straight game, the Celtics relinquished a 20-point third-quarter lead en route to a loss to the Knicks in the Eastern Conference Semifinals — dropping Game 2, 91-90, on Wednesday night at TD Garden.
After sinking just 15-of-60 shots from 3-point range in a Game 1 loss on Monday, the Celtics’ struggles from 3-point range continued on Wednesday.
Boston shot 25 percent from beyond the arc (10-for-40) in Game 2, and only converted on 5-of-28 shots over the final 15:12 of regulation in the third and fourth quarters.
