Randy Cuthbert scored on a six-yard run with 2:48 remaining yesterday as Duke's offense awoke from a 12-quarter slumber to rally the Blue Devils to a 17-16 victory over Army in West Point, N.Y.

Duke (2-3) had not scored a touchdown on offense since its last drive against Northwestern in the second game of the season. The trend continued for most of the game against the Cadets (2-2), who led by 16-3 with 9:38 to play on a two-yard scoring run by Willie McMillian and three field goals by Patmon Malcom.

But quarterback Billy Ray, who alternated with Dave Brown throughout the game, rallied the Blue Devils and spoiled an outstanding performance by McMillian, who was forced from the game by a pulled right hamstring with 13:18 left. Before he was injured, McMillian rushed for 160 yards on 33 carries.

Boston College 19, Rutgers 14: Glenn Foley hit five consecutive passes during an 84-yard drive and Ed Toner ran the ball in from one yard with 19 seconds left for the victory in Newton, Mass.

Boston College improved to 2-2 and Rutgers fell to 2-3.

Massachusetts 16, Rhode Island 13: In Kingston, R.I., Ron Blauvelt's 28-yard field goal with 43 seconds left gave the Minutemen (3-0-1, 3-0) the Yankee Conference triumph over the Rams (3-2, 2-2).

Cornell 20, Harvard 17: A 43-yard field goal by Mathew Hepher gave the Big Red the win in the Ivy League game in Cambridge, Mass.

John McNiff scored both touchdowns for Cornell (2-2) in less than three minutes early in the third period. First, McNiff, who gained 189 yards in 22 carries, broke three tackles on a 66-yard run.

Colgate 30, Yale 17: Dave Goodwin threw for 385 yards and three touchdowns and ran for another as the Red Raiders won in New Haven, Conn.

The victory was the third straight for Colgate (4-1) over an Ivy League opponent and its first win over Yale (2-2) since 1971.

Connecticut 24, Villanova 22: Freshman Nick Sosik kicked a 32-yard field goal with 22 seconds remaining for the Yankee Conference victory in Storrs, Conn.

Princeton 27, Brown 23: Joel Sharp threw a 14-yard touchdown pass to Matt Tarkenton and ran 20 yards for another third-quarter score as the Tigers (2-2, 1-1) rallied from a nine-point halftime deficit to beat the Bruins (0-4, 0-2) in an Ivy League game in Princeton, N.J.

Holy Cross 21, Dartmouth 10: Holy Cross (3-1-1-), favoring the run instead of the high-powered passing attack of quarterback Tom Ciaccio, defeated the upset-minded Big Green (1-2-1) in a nonconference game in Worcester, Mass.
