if they are going to change the bowl affiliation and with the new bcs game coming on the MWC deserves more. The teams that are currently in the MWC (aka the former wac) built One bcs bowl (the fiesta) and built arguable the biggest competitor for the 5th bcs bowl (the holiday bowl).
While I agree the MWC should/might get more bowl attention, other threads have illustrated the difference between the MWC and the BCS conferences. In terms of enrollment, budgets, program success, etc, there remains a notable difference throughout. As for the Holiday Bowl competing for BCS status, I'm sure the Outback, Capital One, Gator and Cotton bowls will argue differently.
In light of the big east being severly weakened by defections the fiesta should look to secure the MWC has its home conference.
In some other threads we directly compared the BE and MWC (Try "General Football", "Will BE get auto bid" or something like that.) I included some tables comparing the schools based on enrollment, attendance, etc. While the BE does not match-up directly with the other BCS conferences, it remained ahead of the MWC. Simply put, the BE had a deeper pool of true BCS candidates than the MWC. Further, the candidates for MWC expansion hurt the conference in other sports or don't add the market for them to notably increase revenue, hence the TCU-only addition. Should CSU exapnd their stadium and grow more popular, or Utah establish a modest tradition, etc, then the MWC will further distance itself from the other non-BCS leagues. Until then, they simply appear lodged as the Best of the Rest.
One reason (The Fiesta should take the MWC champ) is that all the schools are within easy traveling distance. 2. Most of the schools have sizeable alumni in phoenix. 3. there is a history with the teams in the conference.
A. MWC schools not named BYU need to show notable support for their programs (yes, closer bowl games would help) B. The Big 12 schools, while perhaps not all thrilled with the Fiesta, will provide larger and more consistent support, draw more TV $, and do not want a regular match-up against the MWC.
Long term, the MWC must hope the other mid-majors drop further behind the field and that candidates for expansion in Fresno St, Houston and elsewhere begin to nurture themselves toward more BCS worthy status.
