It was the final nonconference game for the Orange (12-1), which begins Big East play at home next week against Seton Hall. Coppin State (1-8) lost its eighth straight road game and dropped to 0-22 against the Big East.
Syracuse's Andy Rautins, starting for the second straight game in place of suspended guard Eric Devendorf, tied Gerry McNamara's school record of nine three-pointers, set against Brigham Young in the NCAA tournament in 2004, and scored a career-high 29 points. Rautins entered the game with 24 three-pointers this season.
Jordan Lee had 12 points for the Eagles and Lenny Young 10.
Jonny Flynn had 10 points and 10 assists for his third career double double for Syracuse, while Paul Harris had 15 points and nine rebounds, Arinze Onuaku 12 points and 10 rebounds, and Rick Jackson 10 points.
Coppin State fell behind by double digits three times and each time rallied to keep the game close. But after McKee's steal and layup and two free throws by Young whittled Syracuse's 11-point lead to 61-57 with 8:35 left, Rautins took charge.
Rautins fed Harris for a driving layup along the baseline and followed with three three-pointers in a two-minute span to give the Orange a 72-59 lead with 5:38 left.
Rautins, who was 9-for-16 from long range, was rarely contested when he shot as the Eagles worried about Syracuse's big men inside. Onuaku and Jackson combined to shoot 11-for-15.
Rautins hit five three-pointers in the first half to keep the Orange in front. After McKee's steal and layup pulled Coppin State within 28-26 with 6:13 left, Rautins hit consecutive threes from the top of the key for an eight-point lead.
After the Eagles rallied behind consecutive threes by McKee to make it 37-32, Rautins fed Jackson for a layup. Flynn followed with two free throws and fed Harris for a layup, and Harris converted a three-point play at the buzzer.
