After nine weeks of football and six Ivy League games for each team, it all comes down to one Saturday.
Brown is clearly in the driver's seat, but if the Bears lose they cannot win the Ivy League title outright.
Harvard, Yale and Princeton are all hoping that Brown slips up and they can take home a piece of the title.
No. 18 Brown (8-1, 5-1) at Columbia (2-7, 0-6)
The Bears are looking for their first-ever outright Ivy title, and would get it with a win.
They seem to have a lock on this one, with the Lions having a historically bad Ivy League season. Columbia has only scored more than seven points in a league game once this year -- and that was in the Penn game, which the Lions still lost by 28.
Columbia is also giving up an average of 32.8 points per game to its Ancient Eight opponents.
Brown, meanwhile, is red hot.
It has won seven straight and scored fewer than 31 points only once this year.
But there are some doubts.
First, Columbia coach Bob Shoop is a Yale graduate. A Lions win would allow his alma mater to win a share of the championship. Hmm.
Or maybe the Bears will not take the Lions seriously. Maybe Nick Hartigan, a finalist for both a Rhodes Scholarship and the Walter Payton Award, will let outside attention go to his head and not play well.
Or maybe not.
"I absolutely don't feel set apart from the rest of my team from all this because, quite honestly, this is all because of them," Hartigan said in an e-mail earlier this week. "If we weren't winning games or the offense was not doing well, I wouldn't be getting any attention and we wouldn't be one game away from making history."
Harvard (6-3, 4-2) at Yale (4-5, 4-2)
"The Game" is usually all about bragging rights, but this year, it also has title implications. The winner of this game would earn a share of the Ivy League title if Brown loses to the Lions.
But that aspect could not raise the intensity of this season-ender above what it already is.
The Crimson is hot, having won three straight, and the Elis are coming off a remarkable comeback victory over Princeton to knock the Tigers out of first place.
Harvard is also trying to do something it has never done -- beat Yale five straight times. The last time the Crimson won four straight over the Elis was from 1919-1922, and Yale ended that streak with a 13-0 win in 1923.
Overall, Yale leads the series 64-49-8 going into meeting No. 122.
The two coaches in this game also have a connection -- they were coaches and roommates at Lafayette in 1981. Harvard's Tim Murphy coached the defensive line while Yale's Jack Siedlecki coached the offensive line.
Dartmouth (2-7, 1-5) at Princeton (6-3, 4-2)
While Princeton still has a chance to win a share of the Ivy title for the first time since 1995 with a Brown loss, apparently much more is on the line here.
For the second time ever, the two teams are playing for the 1917 Sawhorse Dollar.
This started as a one-dollar bet in 2002 between two business acquaintances, who happened to be alumni of the respective teams.
When Princeton won, the Dartmouth representative, T.J. Rodgers, sent his associate Tad LaFountain the oversized World War I-era dollar bill instead of the more conventional one found in banks and vending machines all over America.
Then LaFountain called Princeton coach Roger Hughes and got the two teams to play for this now-framed piece of paper, which has a picture of the Pilgrims landing at Plymouth Rock and a portrait of George Washington.
Move over Harvard and Yale -- there's a new Ivy League rivalry that everyone should really be paying attention to.
