It was Plomb's 15th 20-point game career, fifth this season. Kyle Wilson scored 14 points with four 3-pointers. The Black Knights are off to a 7-2 start for the second consecutive season.
Bryant (2-8) was led by 17 points from Nisre Zouzoua while Dan Garvin and Marcel Pettway each finished with 13 points and 10 rebounds - the first time this season two Bulldogs have double-doubles in the same game.
Army's 14 treys is a season high, and the most made against a Division I opponent since the Black Knights dropped 15 3s on Marist Dec. 4 2012.
Army coach Zach Spiker wore a gray v-neck sweater on the sidelines in honor of the 50th anniversary of Bob Knight's first-career coaching victory (Army 71-62 over Worcester Tech on Dec. 8, 1965).
