Alabama retained its season-long lead in the College Football Computer Composite rankings this week, but Ohio State's victory Saturday at Oklahoma cut into the Crimson Tide's lead by 80%.

After Week 2, Alabama was No. 1 in every one of the five computer formulas that fed the Bowl Championship Series standings and now combine for the CFCC. This week Alabama is No. 1 in three of them with Ohio State atop the other two.

Ohio State is alone in its ascendancy, however. Last week the Buckeyes' lead on No. 3 Clemson was about ⅓ of a ranking spot. This week the gap is the equivalent of 2⅓ spots.

Not surprisingly, Louisville was the biggest mover among top 25 teams, rising 13 spots to No. 7. Overall the biggest decliner was South Alabama, which dropped its second consecutive Sun Belt game Saturday after opening its season with a win at Mississippi State. The Jaguars fell 21 spots while the team that beat them, Louisiana-Lafayette, rose 21.

The College Football Computer Composite combines five of the computer formulas used in the former BCS standings to remove the human element from college football rankings. It is compiled by taking the geometric mean of rankings formulated by Richard Billingsley, Wes Colley, Ken Massey, Peter Wolfe and Jeff Sagarin.

Among the metrics feeding the CFCC are wins and losses, strength of schedule, home-field advantage, recency of game and, in Massey and Sagarin's case, margin of victory.
