I just told the guys to settle down and keep them out of the paint. Once they get in the paint they finish and create havoc.Denton (17-15), which trailed by as many as 13 early in the fourth quarter, cut the deficit to eight on a basket by Michael Jackson with 4:40 to play.

I just told the guys make sure you grab the ball with two hands.Four Bulldogs scored in double figures led by Chasten King with 19. Gales added 16 points and Spencer Franklin chipped in 15.
