-- If Yale loses at Brown, it still can win the outright title with wins against Princeton and Harvard.

-- If Penn beats Princeton and Columbia pulls the upset of all upsets and beats Harvard, Yale would clinch a tie of the Ivy League title with a win at Brown Saturday.

-- Here's a crazy scenario, but possible. Yale beats Brown, then beats Princeton in a 12:30 game Nov. 11. Penn beats Harvard in 1 p.m. game the same day. Yale loses at Harvard the 18th, still wins the outright title, but never gets to celebrate on the field.

-- Technically five teams still have a chance to win league: Yale, Harvard, Princeton, Penn and Brown.
