Last night, Grant Williams took the 50th three point attempt of his playoff career, qualifying for the all time leader board. He has hit an astonishing 28 of those 50 attempts, for a career 3PT% of 56% in the playoffs. That is number one all time by a substantial margin: the difference between him and second place is the same as the difference between second and fourteenth. He's almost ten percentage points better than Steph Curry (47%).
The title more or less says it all: Grant is officially the most accurate 3PT shooter in NBA playoff history. Hail to the new King.
