Date the end of the 2000s in college football Oct. 31, 2009. On that Halloween, No. 4 USC—the most successful, glamorous program of the 2000s—traveled to No. 10 Oregon and returned home a 47–20 loser.
Out went the hard-nosed '00s of coach Pete Carroll, running back Reggie Bush and linebacker Rey Maualuga; in came the space-age 2010s of coach Chip Kelly, quarterback Marcus Mariota and running back Kenjon Barner. The Ducks never won a national title, but their DNA spread throughout college football in the social-media and superteam decade.
