here a link describing it

they actually never wanted 16 (at that time) they wanted to go with 12 but their hands were forced. it was unknown grounds at that time to have so many and it wasnt even remotely thought out
espn already told them from the get go before expanding that the number of teams were meaningless they were getting the same contract money either way and a second for the championship game so anything above 12 meant nothing.
they original were already in talks with big west schools and practical had it finalized with the teams they wanted but then the swc broke up and "better teams" than the ones they were taking to became available. so they took both.
they had a hard time deciding division had a hard time agreeing with anything. pods were the only way to get people in the geographical fits they wanted but even with that certain teams wanted permanent division and didnt like pods, and when they tried to return to divisions the original problems of who's in what division re-happened and a few teams even threatened indy.
the breaking point was when everyone who wanted to be in the same division but couldnt because of geographical reasons/upsetting other teams just left and formed the mwc
the biggest difference is that the age of football has changed
1) the wac broke up because of desired rivalries, that isnt important anymore in 2013, its about money, we'll all sellout our rivalries for money in heartbeat in todays world
2) indy was a legit option then so walking out was easy
3) forming a new conference wasnt as difficult as it is today with ncaa contracts, bowl stuff & unrealistically expensive conference buyouts making a new football conference isnt that easy
most of the WAC problems wouldnt be in a AAC problem, 1) we'd be more inclined to work out our problems as there arent many plan b's 2) divisions would be simple east and west, west = 4 byu/mwc, the 2 Texas, tulsa and tulane 3) many other conferences have gone large numbers not 16 but enough to show a large conference can work, both the big 10 and pac 12 would go to 16 if they could get the teams they want.
