Big Blue O

But the biggest challenge for Harvard lies on the defensive end of the ball in stopping an in-gear offense that has racked up 65 points in the last two games.

Kehler has passed for 651 yards and five touchdowns and run for another 409 yards on the season. Senior Kevin Callahan is the big-threat running back out of the wishbone, racking up 461 yards on the ground, leading the team with 17 receptions and passing for two touchdowns in as many attempts.

But the Toads, as the Yale offensive line is known, are vastly undersized compared to the Harvard defensive line--a plus when running the wishbone but a big problem if/when the Elis have to go to the air. Harvard has already set a team record for sacks in a season with 46, including 11 by linebacker Joe Gordian.

The key for Harvard is forcing Kehler to the air, where more likely than not Harvard's secondary will come up with a big play or the front seven will come up with a big sack. As Restic said, "If we let Kehler and Callahan run the option up the field, they'll control the ball all day."

And, of course, if Harvard will be at its most dangerous when it forces Yale to bring on punter Greg Bowman. The Crimson has already blocked six punts this season and tipped three other Rob Sims punts last week.

"Their kicking game has been devestating," Cozza said. "They're blocking punts all over the place and their kickers are effective."

Harvard junior Scott Johnson has connected on 11-of-14 field goal attempts this season, including a game-winner against Princeton four weeks ago and a career-high 43-yarder last week. Johnson's three misses have all been at least 43 yards long. Yale's Ed Perks is comparably dangerous, connecting on a 52-yarder this season and missing only two field goals inside 40 yards.
