Celtics rookie Grant Williams on 3-pointers in his first 20 games: 0-for-25.

0-for-25!

Nobody else has ever started a season that cold.

Of everyone else to attempt at least 25 3-pointers in their first 20 games, nobody made fewer than two. Of everyone else to miss all their 3-pointers in their first 20 games, nobody attempted more than 17.
