ITHACA, N.Y.—By the time Cornell took possession of the ball for the third time Saturday afternoon with 3:49 remaining in the first quarter, the Harvard football team—which entered the game ranked No. 23—had already posted nine more points than the Big Red had total yards.

The Crimson (4-0, 2-0 Ivy) defensive unit dictated the game’s tone from the first snap, limiting Cornell (1-3, 0-2) to fewer than three yards per play and allowing the Big Red inside the 20-yard line just twice en route to a cushy 27-0 victory, Harvard’s first shutout in Ithaca in 110 years.

Under the yoke of a stifling Crimson rush headed by junior linebacker Bobby Everett and his one-and-a-half sacks, Cornell managed just four yards of total offense and no first downs on its first two possessions of the game.

The Big Red’s third drive appeared to offer more promise, as quarterback Mick Razzano drove his squad 56 yards downfield and into scoring range.

But senior defensive end Brian Garcia knocked the ball free as Razzano attempted to scramble his way inside the red zone and junior defensive tackle Matt McBurney recovered and ambled 34 yards the other way to establish Harvard—which already led 13-0—just inside Big Red territory.

“We made big plays,” Crimson head coach Tim Murphy said. “We played great backs-to-the-wall defense.”

That clutch defending was put to its greatest test as the first half wound down, with the Big Red driving inside the Harvard five-yard line with under a minute left.

After taking possession on the Crimson 38 with 4:09 remaining, Cornell pounded the ball into a drained defensive line, rushing on six consecutive downs—highlighted by four rushes by tailback Andre Hardaway that netted 20 yards—to advance inside the Harvard 15.

A short pass and another Hardaway rush set up third-and-one on the five-yard line with the clock slowly ticking away. McBurney stuffed fullback Todd Newell’s push towards the marker, setting up fourth-and-inches with half a minute to go. Once again the call was for Hardaway, but this time the Crimson defense was ready.

The defensive line rebuffed the Big Red line’s push while senior cornerback Benny Butler—who led both teams with 12 tackles and was named the Ivy League Defensive Player of the Week—and senior free safety Chris Raftery maneuvered through the line to plant Hardaway inches from the spot, securing a 20-0 Harvard lead at the half.

“If they had scored at halftime, [it’s a] completely different game,” captain and linebacker Dante Balestracci said.

But with the defense surrendering just 138 yards of offense and no points in the first half, the lead junior quarterback Ryan Fitzpatrick and his unit had established 39 seconds into the second quarter held up.

“We came out and really dominated the line of scrimmage,” Murphy said. “We kind of cruised to an easy 13-0, 20-0 [lead]. Any time you can do that with our defense, I’ll take that.”

With the defense forcing punts on each of Cornell’s first two possessions and the fumble on the third, the Crimson offense’s average starting point after the Big Red’s first three possessions was its own 40-yard line. But the second offensive possession was drastically different than most of Murphy’s explosive passing sets.

Despite injuries to five of its top eight offensive linemen, Harvard began a 62-yard march downfield with 11:39 remaining in the first quarter that was highlighted not by crisp passes from Fitzpatrick but by sharp runs by freshman tailback Clifton Dawson. The rookie gained 31 yards on five carries on the drive, including a 16-yard burst on a delayed rush out of the shotgun that set up the opening tally. Sophomore Ryan Tyler caught a pass along the left sideline for a six-yard gain and on the next play punched the ball in from the five to put the Crimson up 6-0 following senior kicker Adam Kingston’s botched extra-point try.
