The Ivy League championship goes on the line at 1 p.m. today in the Stadium as Harvard hosts Penn.

A Penn victory would give the Quakers their fourth straight league crown, while a Harvard victory would deadlock the two teams in a tie at the top with one week left in the season.

Penn (6-1-1 overall, 5-0 Ivy) needs to win only one of its remaining two contests to clinch a share of the title, but the Quakers stand to clinch their second consecutive outright championship if they can get by Harvard today.

For Harvard (6-2, 4-1), there is no tomorrow. An earlier loss to Princeton at the Stadium has left the Crimson a game behind the Quakers in the Ancient Eight standings, and turned today into a must-win.

If Harvard wins today and then goes on to defeat Yale next weekend in The Game, the Crimson will snare at least a share of its first league crown in two years. If Harvard wins its last two games and Penn loses its final two, the Crimson will claim its first outright title since 1975.

But a Crimson victory today will not come easily. Penn has won a record-tying 13 consecutive Ivy League contests since Harvard shut out the Quakers, 28-0, in 1983, and a win today will give Coach Jerry Berndt and his troops a record-shattering 14th.

And Penn--coming off a 27-27 tie of highly touted Colgate--is red-hot. The Quakers were behind 17-7 in last week's game before reeling off 20 unanswered points.

But Penn's greatest comeback this year came a week earlier against Princeton. Playing a Tiger squad coming off its come-from-behind victory over the Crimson, the Quakers fell behind 21-0 at halftime, only to roar out of the locker room and score five straight touchdowns on their way to a 35-21 win.

Harvard itself is no stranger to comeback victories. The Crimson staged its greatest fourth quarter rally ever last week at Holy Cross, scoring 21 points in 41 seconds to defeat the Cross, 28-20.

Besides comeback capability, however, about the only thing the two teams have in common is a great running back.

Harvard's Robert Santiago had the fifth best rushing day in Crimson history last week, running for 185 yards and one touchdown. He also threw the game-winning scoring strike in the fourth quarter.

Santiago has been the Crimson work-horse all year, carrying the ball 126 times for 657 yards--nearly half of Harvard's ground total--for a 5.2 average.

Although he started slowly this season, the senior halfback has improved with each game, and last week's performance was as good any he put on last year--when he led the lives in rushing.

But Santiago doesn't lead the league in rushing this year; Penn's Rich Comizio does.

Running behind an excellent veteran line, Comizio has fulfilled the promise he showed at the beginning of the year before he went down with a pulled hamstring in the pre-season.
