With Coleman dominating in the paint and getting six points, the Rams grabbed a 17-4 lead by the time the game was five minutes old.
The rest of the game amounted to a chase, one that J-D didn't always handle with ease. Shen got big performances from Dan Lee (19 points) and reserve Manny Hernandez (17 points) and played on even terms the rest of the first half, only trailing 38-26 at the break.
J-D tried to get away, expanding the lead to 44-29 in the third period, but Shen countered with a 10-2 run as it took over on the boards, getting all kinds of second and third shots.
As the fourth quarter began, J-D's lead was just eight, 57-49, and the struggles on the boards had head coach Bob McKenney worried about possible fatigue.
But the Rams answered like a champion would, as Coleman regained control of the paint and J-D went on a decisive 10-0 run, blanking Shen for more than four minutes.
Coleman finished with 18 points, while Kearse got 17 points and Jailaan Kinsey came off the bench to earn 10 points. Cavanaugh had nine points.
J-D is going back to OCC twice more next weekend, first for a Friday game against Buffalo-area power Nichols, then to meet Fulton on Saturday night.
