Not looking at this from an academic, locational, or even other sports standpoint, but if the Mountain West would have a REALLY good case for a BCS autobid if they add Boise State, Fresno State, and Hawaii.
The first data that the BCS uses to determine the autobids is the ranking of the highest-ranked team in the final BCS standings each year. From 2004-07, the Mountain West champion has been ranked in the Top-25 of the final BCS Standings. However, those rankings are 6th, 14th, 20th, and 17th respectively with an average finish of 14.3. IF you add those three schools, that average ranking jumps up to 9.5, whereas the Big East has an average finish of 9.
The second qualification data includes the number of teams in the top 25 of the final BCS standings each year. Currently, the MWC averages 1 team to the Big East's 2.75 teams from 2004-07. If they add those respective teams in the WAC, they'd average 2 teams in the final BCS standings each year.
Unfortunately, I haven't been able to find any data to analyze the final qualification - the final regular-season rankings of all conference teams in the computer rankings used by the BCS each year. I would have a hard time believing that the BCS wouldn't give an autobid to the MWC if they expanded to 10-12 teams and added Boise State.
Here's what I would have for the divisions...
West: Boise State*, Fresno State*, Hawaii*, New Mexico, UNLV, San Diego State
Mountain: BYU, Utah, TCU, Colorado State, Wyoming, Air Force
With the expansion from 8 to 10 teams in the BCS thanks to the championship game and a non-automatic qualifier getting in for the third straight year assuming someone crashes this year in the MWC + Boise State, I think they would strongly consider giving the conference an autobid if they expanded to 12 teams.
