Intraconference Variety at the Top

I was thinking about the Pac-10, and how for the past decade it's been USC and 9 teams named Fred (or so it seems).  So I decided to compare each conferences' performance in the last decade (2000-2009 regular seasons) by the number of different teams that made it to a BCS bowl game, and by the number of different teams that won a BCS game.  Here goes:

Big Ten: Made it: Purdue, Illinois, Michigan, Ohio State, Iowa, Penn State (6/11).  Won: Ohio State, Iowa, Penn State (3/11)

Big East (current members): Made it: Pitt, WVU, Louisville, Cinci (4/8). Won: WVU, Louisville (2/8)

ACC (current members): Made it: Miami, FSU, Maryland, Va Tech, Wake Forest, Ga Tech (6/12) Won: Miami, Va Tech (2/12)

SEC: Made it: Florida, LSU, Georgia, Auburn, Alabama (5/12), Won: Florida, LSU, Georgia, Auburn, Alabama (5/12)

Big 12: Made it: Oklahoma, Texas, Colorado, Kansas State, Kansas, Nebraska (6/12) Won: Oklahoma, Texas, Kansas (3/12)

Pac-10: Made it: Oregon State, Washington, Oregon, Washington State, USC (5/10) Won: Oregon State, Washington, Oregon, USC (4/10)

Conclusions:

• When it comes to getting the greatest percentage of different schools into a BCS game over the past decade, nobody tops the Big Ten at 54.5%, and every other league except the SEC (41.7%) was at 50%.  Everyone loves to talk about how top-to-bottom competitive the SEC is, but by this metric, it ranks as the single most top-heavy league.  By contrast, the Big Ten ranks as the most competitive, amplified by the fact that each team that made it to a BCS game made it to at least two, with the exception of Purdue.
• The Pac-10 and SEC win BCS games like it's their job. 41.7% of SEC teams and 40% of Pac-10 teams won a BCS game in the aughts.  The closest league to them was the Big Ten, where 27.3% of its teams won a BCS game in the same decade.  Granted, the last time a team not called USC won a BCS game was Oregon in the 2002 (2001 regular season) Fiesta Bowl. Regardless, those 2 leagues have clearly had the widest variety of excellent (as measured by BCS game winning) teams in the aughts.
• The Big East compares well to the other leagues, even after the ACC allegedly raided its best teams. 50% of its current membership has been to a BCS game in the past decade, which is worse only than the Big Ten, and 25% of its current membership has won at least one BCS game, which is only worse than the SEC, Pac-10, and Big Ten, and much better than the league that supposedly took all of its best teams, the ACC (16.7%).
• The top of the ACC stinks and lacks variety.  It was better than only one league (the SEC) at producing a variety of BCS paricipants, and dead, distant last at producing a variety of BCS winners.
• Congratulations to the Big 12 on being average at both producing a variety of BCS participants and BCS winners.  You are the Big East.  Don't you forget it.  Now fork over Texas.
• Michigan didn't win a BCS game this decade?  And Louisville, Kansas, WVU, and Oregon State did? Find somebody who would've predicted that before the 2000 regular season.
