Alot still depends on what happens to the Big East despite rumored invitations to Air Force, Boise State, Central Florida, Houston, Navy, and Southern Methodist. Any teams joining the Big East must realize that realignment of current Big East teams is not over. Per the West Virginia suit against the Big East state what we all know, that Cincinnati, Connecticut, Louisville, Rutgers and South Florida are all leaving. In fact, there may not be a Big East football conference if the Big 12 takes Cincinnati, Louisville, and South Florida while the ACC (or less likely the B1G) takes Connecticut and Rutgers for 2014.
The demise of the Big East, will best position the Alliance of C-USA and MWC to gain an automatic bid to the BCS. Whether each conference should have its own championship game is open for discussion due to NCAA rules. The Alliance championship game must be played in time for the BCS selection, as well as for the loser to be directed to its own bowl. Most likely this will be the first weekend in December, same time as the other conferences championship games. If there is a conference championship game then it will occur during "rivalry weekend" of Thanksgiving. The differentiation during both weekends might favor more for the C-USA and MWC conferences: Alliance championship rather than conference championship and conference championship rather than conference rivalries. But since the schedule is moved forward one week, and since the season cannot be moved forward one week (NCAA rules) then the Alliance teams may lose its bye week.
For each conference lets look at what the membership would be like, with and without losses.
Losing Central Florida, Houston and Southern Methodist the conference could stay at 9, add one to go to 10 (Louisiana Tech from the WAC) or add three (Louisiana Tech, upcoming UT San Antonio, and Texas State, all from the WAC). The two new Texas teams could replace Houston and Southern Methodists in the division line up, while Louisiana Tech could be in the East to replace Central Florida or in the West with Tulane moving East. If the three teams lost were Central Florida, Southern Mississippi and Tulane, then the 6 Texas teams would be West, and Tulsa and Louisiana Tech would be in the East.
Losing just one team like Central Florida the conference could stay at 11 or take Louisiana Tech (WAC) to go back to 12. Of the one team lost was Tulane, then Louisiana Tech would slide right in Tulane's spot.
Losing 2 teams (Boise State and Air Force) the conference will need two replacements and again it will be the WAC that will be raided: Utah State fills a geographic deficit, leaving Idaho, New Mexico State, and San Jose State. All four teams could take the conference to 12. Its division could be split East (Colorado State, Idaho, New Mexico, New Mexico State, Utah State and Wyoming) and West (Fresno State, Hawaii, San Diego State, San Jose State, Nevada, and Nevada Las Vegas).
It is quite possible that like the Big East, the WAC could be eliminated as a football conference. I think conference consolidations from 11 to 9 could be a good thing and one step further to equalizing the conferences with a playoff or BCS.
