<p>i dont think it's really a debate who penn's rival is. It's clearly Princeton (in terms of sports/school spirit). Case in point: When you play NCAA Football 2006, and have Penn vs. Princeton, an icon pops up saying "rivalry matchup" or something along those lines.</p>
<p>Also, when you start playing it lists the past times the two teams met and who won. Penn I think has won at least the last 10 or so years.</p>
