Boston Celtics guard Marcus Smart leapt up high in the air to reject Brooklyn Nets third-year center Jarrett Allen on Tuesday in the two teams’ Tuesday night matchup. Smart, 25, then gave Allen the classic Dikembe Mutombo finger wag (via Taylor Snow).

Smart entered the 2019-20 season as the longest-tenured member of the Celtics, and his energy on defense has been crucial as Boston jockeys for playoff seeding in the Eastern Conference postseason behind the Milwaukee Bucks and Toronto Raptors. Smart has emerged as a super sub, starting in 34 of his 48 appearances this season and turning into a Swiss Army knife for head coach Brad Stevens’ squad.

Smart has averaged a career-best 12.9 points, 3.7 rebounds, and 4.9 assists in 32.1 minutes per game, shooting 38.0 percent from the floor, 35.5 percent from deep, and 81.5 percent from the free-throw line.

Smart, at 6-foot-3, overcame an eight-inch difference to block Allen and rub it in his face with the Mutombo celebration.
