Just meandering out loud...does a conference make a program, or vice-versa?
On one hand I think SMU and SDSU are lowly sports brands for the mighty Pac-12 to be considering (but, sure...beggars can't be choosers...) - but 5-7 years from now it's not wholly unreasonable to imagine SMU cracking the Top 12 and getting a playoff berth and doing its part to keep the Pac-12 relevant.
Also...I will be interested to see what the conference landscape looks like 15-20 years from now - how long will programs like Florida, Texas, USC, and so on be content winning one conference title every 8-9 years, before they take another look at Big XII, Pac-12, etc. and see an easier path to conference titles and playoff berths? And will tv money still be as prolific?
