The Boston Celtics had themselves a day in Game 1 against the Milwaukee Bucks on Sunday, running away with a stunning 112-90 victory over the top-seeded team in the Eastern Conference. Jaylen Brown got in on the fun with 19 points on 8-of-14 shooting, and two of those points came in style via monster dunk on Milwaukee Bucks superstar Giannis Antetokounmpo:

The young Celtics swingman explained why he didn't flex after the dunk:

While a little trash talk is always fun, Brown wanted to stay smart and avoid getting into any trouble in this key playoff game. Instead, the youngster simply let his game do the talking, and he made sure it was some really loud talking.

Brown and the Celtics took it to the Bucks from the opening tip, dominating most of the game outside of a few stretches. Boston went up by as many as 15 points in the first half, and then after Milwaukee came back and even took a lead in the third quarter, the Celtics turned on the jets to turn the game into a blowout.

Jaylen Brown enjoyed a breakout postseason last year with Kyrie Irving and Gordon Hayward out, and he has been playing really well in these playoffs. The confident 22-year-old shot 21-of-32 from the field over his last three games, all Celtics wins as they've started this postseason 5-0.
