When one thinks about Boston College's football program, one recalls a number 20 ranking in the pre-season national polls and the new "big time" gridiron image of the cross-town folk.

The Eagle's junior varsity, the boys who will make or break the future of that revamped program, visited Soldiers Field yesterday for what they thought would be just another routine tune-up.

And although the B.C. team ran its unbeaten string to four with a 16-7 triumph, Harvard's tenacious freshman gridders didn't exactly swoon in the presence of the awesome unit.

The visitors grabbed an early 7-0 lead in the first quarter with a 60-yard drive. But after Perry Carter's eight yard scamper for paydirt, Harvard's defensive crew shut the door for the remainder of the half. Two

Harvard's offense, which had stalled for much of the first half, used the big break to get untracked. Fullback Matt Granger, who along with Ralph Polillio and Joel Boone were the Crimson workhorses on the ground, ripped off a 19-yard gallop to the B.C. 18.

Under the guidance of quarterback John Crumpler, Harvard scored on a two-yard plunge by halfback Boone. kicker Gary Bosnic split the uprights on the PAT for a 7-7 halftime deadlock.

A 21-yard field goal by Toppa gave B.C. a lead they were never to relinquish in the third period. The Eagles put the contest out of reach midway through the final stanza on a 43-yard scoring drive.
