WATCH: Grant Williams’ hilarious bench celebration to Jaylen Brown’s 3

Boston Celtics rookie Grant Williams has an awesome reaction to a wide-open Jaylen Brown 3-pointer.

Sometimes, you can’t help yourself when you see a play that good.

Boston Celtics rookie Grant Williams had himself quite the celebratory dance when teammate Jaylen Brown drained a wide-open 3-pointer off of a Marcus Smart dime, bobbing and weaving side to side with joy as the Celtics laid a 128 – 101 beatdown on the Sixers to take a two-game lead in their first round series.

Boston’s bench was as big of a factor in the team’s first game without veteran forward Gordon Hayward — who will miss about four weeks with a sprained ankle sustained late in Game 1 — with every active player on the roster scoring save Robert Williams III.

Grant had himself a solid outing of his own, chipping in 9 points and 6 rebounds in 21 minutes of game time, with Boston threatening to sweep Philadelphia despite losing Hayward’s services.

Given the general trend of this series, it’s easy to see why Williams was so enthused — watch the video embedded above to see it for yourself.
