If your definition is the league that is most top-heavy, the SEC is the only choice. Alabama and Florida are ranked 1-2 in the year’s first BCS rankings, and an overwhelming six teams are ranked in the nation’s top 12. At this point, you can’t rule any of them out of national championship contention, which would give the SEC its sixth straight national title.
But in terms of pure top-to-bottom depth, the BCS poll indicates that you can’t do any better than the Big 12, which has 70 percent of its teams in the Top 25. Kansas State leads the way at No. 4. They are followed by No. 9 Oklahoma, No. 13 West Virginia, No. 17 Texas Tech, No. 23 TCU, No. 24 Iowa State and No. 25 Texas.
