"I was disappointed the way we came out falling behind 20-5 in the first five minutes, but from that point on we did a really good job and stepped up to the challenge and battled back with all the tough shots they made, we were down six with the ball with under three minutes left so there were a lot of opportunities there for us," said Coast Guard head coach Kevin Jaskiewicz.
"Kevin Alvarez and Avierre Conner were both really efficient off the bench for us tonight as they combined for 30 points and both of them have been practicing very hard so I was not surprised at how well they played tonight. I really liked the way our guys competed tonight with five guys in double figures and only turned the ball over five times, it was a good performance," added Jaskiewicz.
Coast Guard is back in action on Wednesday night in the New England Women's and Men's Athletic Conference (NEWMAC) opener at Wheaton at 7 p.m.
