A Butterfly Flaps Its Wings and Bowl Lineups Change

One of the BCS computer polls has an interesting widget where you can change history and see the effects on the polls. If the Tar Heels had just managed to slip by Georgia Tech, Wisconsin, Louisville, Miami, and Maryland, they'd be chasing Texas for the title. History is built on the littlest of things.

(But seriously, take a gander at the chaos caused in the Top 5 if you change the Northwestern/Arizona State result.)
