After the Harvard football team opened up a commanding 49-3 lead at the half, starting quarterback Colton Chapple was pulled, allowing his backup, sophomore Conner Hempel (#14), to take his first snaps of the 2012 season. In the Crimson’s 52-3 rout of Holy Cross on Friday night, Hempel completed four of seven passes for 36 yards.

The Harvard football team’s game against Holy Cross Friday night at Harvard Stadium shared few similarities with last year’s 30-22 Crusaders win. The Crimson (3-0, 1-0 Ivy) offense could not be contained by the Holy Cross (0-4) defense or a steady rain, scoring a touchdown on each of its first seven possessions to finish the first half with a 49-3 lead and the game with a 52-3 win.

Harvard displayed its offensive firepower early, scoring just over two minutes into the game on a 10-yard strike from senior Colton Chapple to junior wideout Ricky Zorn. Zorn finished the half one yard shy of 100 yards receiving while Chapple threw for 260 yards and four scores.

“[Since] there wasn’t a lot of wind, there was no question we were going to throw the ball,” Crimson coach Tim Murphy said. “We take great pride in being able to play in any conditions.”

Chapple ran for another score before being pulled at halftime, while senior running back Treavor Scales, who ran for over 100 yards in each of the team’s first two games, added 82 yards in the first half.

Harvard’s 49 first-half points broke the school record, which dated back to 2005.

“It’s a credit to the guys up front, seeing as how we can do pretty much whatever we want, whether it be throwing the ball or running the ball,” Chapple said. “Keeping [the defense] on their toes is something that we were able to do in the first half.”

Holy Cross came out of the gates just as explosively, gaining 65 yards on its first play from scrimmage down to the Crimson 12.

But the Crusaders were unable to punch it in, eventually settling for a field goal. From that point on, Holy Cross gained only 26 yards and two first downs in the first half.

As dominant as Harvard was on offense and defense, its special teams play was equally impressive early on.

On the Crusaders’ first of nine punts, Crimson sophomore Connor Sheehan blew through the line and blocked the kick. Senior D.J. Monroe scooped the ball up and ran it back for a touchdown.

“Connor Sheehan is a kid who has a knack for that,” Harvard coach Tim Murphy said. “He has tremendous closing speed in a short space; he’s becoming a really huge special teams player for us.

“That [blocked punt] was the key play of the first half,” Murphy added. “It just really put us over the top.”

On Harvard’s final drive of the half, Murphy elected to send out backup running backs senior Rich Zajeski and freshman Paul Stanton Jr. instead of Scales.

The pair of replacements proved just as dynamic. Stanton started the drive with two rushes for 33 yards, and Zajeski finished it with a four-yard touchdown run. In between, Chapple connected with senior Kyle Juszczyk for a 51-yard gain.

The Harvard backups got more playing time in the second half as few Crimson starters saw the field.

Sophomore quarterback Connor Hempel led the team on a 58-yard drive that culminated in a field goal to start the second half.

Harvard did not score after that, as the offense played conservatively up 49 points. In the final few minutes of the contest, freshman signal caller Scott Hosch got time behind center as well.

Despite a lack of scoring, Stanton racked up nearly 80 yards on just eight carries and also returned a kickoff 42 yards on his first touch in college football.

“I went back and watched [Stanton’s] highlight film in the summer about 10 times saying, ‘I think this kid’s really good,’ and you know what? He’s really good,” Murphy said “He gave us a huge lift. He showed us he’s a real player at this level.”

While the Crimson offense cooled off, Harvard’s defense kept up its pressure for the entirety of the game.

Holy Cross’s best chance to score in the second half came early in the fourth quarter as the Crusaders drove the ball to within the Crimson’s five-yard line. After an incompletion and two thwarted running attempts, Holy Cross went for a touchdown on fourth down from the three, but a pressure-induced incompletion ended the threat.

The Crusaders’ starting signal caller was eventually pulled from the game but was put back in after the backup fumbled back-to-back snaps, the second of which was recovered by Harvard.

Holy Cross finished with just 191 yards offensively compared to the Crimson’s 520.
