While Dartmouth was showing itself to be a serious Ivy contender this weekend, at Harvard's expense, the biggest news from around the league Saturday was that Yale really is bad this year and Brown is a dark horse worth watching.

Columbia 21, Yale 18

For the first time this season, the Columbia defense held an opponent to fewer than 20 points. In the meantime. All-Ivy quarterback John Witkowski compiled his typically impressive stats as the Lions broke a 10-game losing streak--by holding off the Elis in the Yale Bowl.

Witkowski completed 20 of 27 passes for 259 yards, setting a new Ivy career record for total offense--4369 yards--in the process. He hit Don Lewis and Dan Upperco on TD passes.

Columbia is now 1-4, 1-3 in the league. Yale is 0-2 in the Ivies, 0-5 overall, its worst start ever.

Brown 14, Cornell 3

Taking a 3-0 first-quarter lead for the second straight week. Cornell collapsed in the second half, managing only three first downs while allowing two Bruin touchdowns.

Playing before the home fans, Brown QB Joe Potter had a strong game, completing 16 of 29 passes and scoring the second touchdown on a 29-yard run in the fourth period.

Brown is 2-1-1 in the Ivies, 2-2-1 overall. Cornell is 0-2-1 in the league, plus two non-Ivy losses.

Penn 28, Lafayette 20

Penn stunned the team ranked 17th nationally among Division I-AA schools after taking a 21-0 halftime lead.

Lafayette's Frank Novak, the top ECAC Division I-AA passer, gained only 154 yards through the air. The Quakers held their visitors at Franklin Field to only 78 yards on the ground.

Penn is 2-0-1 in the Ivies, 3-1-1 overall.

Navy 37, Princeton 29

Navy running back Napoleon McCallum was unstoppable in the first half, and Princeton quarterback Doug Butler led a strong comeback in the second, but the Midshipmen held on, leaving the Tigers at 2-1 in the Ivies, 3-2 overall.

Both standouts entered the NCAA record books. McCallum set a new mark with 32 carries in the first half alone. Butler, 25 for 55, set a new collegiate standard for the most pass attempts in a game without an interception.
