Video: Grant Williams produces career high 18 points in Celtics win over Pistons

Whenever you can shoot just 10 times and finish with 18 points you know that that was an efficient night of basketball. Celtics rookie Grant Williams had that night yesterday, going 8 for 10 from the field (two of those field goals being 3-pointers) on his way to his career high. Small sample size and all, but Williams has shot 57% from behind the arc the past 4 games. This of course comes after missing his first twenty-five attempts to begin the season. Williams showed the ability to hit from behind the NBA arc during summer league play and in order to be a productive player in the league he'll have to continue to improve in that area.
