Since the start of the 2005 season, a No. 1-ranked team -- we're counting AP polls or BCS standings, depending on what part of the season it was -- has lost 15 times. It happened just once each in 2005, 2006 and 2008, but it has happened in each of the last three weeks. Because those three drops -- the Alabama Crimson Tide, Ohio State Buckeyes and Oklahoma Sooners -- all happened as they were the road team at the "College Gameday" site, many are focused on the Oregon Ducks heading to face the USC Trojans in Los Angeles.
In reality, though, the Mississippi Rebels -- the same team that opened the season by allowing 49 points to Jacksonville State -- could stun the BCS No. 1 Auburn Tigers on Saturday. There are four trends to knocking off a No. 1, however improbable it may seem. Ole Miss does have a shot here.
