Celtics-Mavs: Best photos from Jaylen Brown's one-handed poster - ESPN

Remember when Jaylen Brown was the runner-up to Mac McClung in the dunk contest during NBA All-Star Weekend in February?

Unfortunately for the Dallas Mavericks, it turns out the Boston Celtics star might have been saving his best jams for the NBA Finals.

Brown threw down a thunderous transition dunk in Game 2 and kept up his high-flying efforts by putting P.J. Washington on a poster in Game 3.

While the video above shows the play in all its glory, these frames further put the dominant play into perspective.
