Bowl Wins Not Good Indication of Best Conference
Okay, I think you have twisted the numbers somewhat.
When we look at bowl games, most bowls are set up in order to get comparable teams - that is, teams that are somewhat well-matched for one another. Sure, there is geography and how the supporters of the team travel, but you are not going to see a #4 team battle a nobody.
If you look at the rankings thus far for this year, the Mountain West is doing the best against all other conferences. They are 4-1. Does that mean they are the best conference? Hardly.
The Southwest conference was the conference I supported when it was around, and there were some great teams in that conference. Their record was not all that good in bowl games, but many of the best bowls in the 60s and 70s included teams from that conference (Arkansas, now in the SEC, was a member of the conference).
Personally, I think the SEC is historically the strongest conference, but it has more to do with me evaluating games. I like watching SEC teams play, and I think they have some of the strongest teams now. I just don't think bowl wins and losses are a good indicator or argument for placing one conference ahead of another conference.
Wisconsin had a really good team this year, but they were beat today by the TCU Horned Frogs. I would think if they were in the national championship game (the TCU Horned Frogs), they would give the SEC a run for its money. Wisconsin looked nearly invincible playing other Big 10 Teams.
