There has been many rumors as to if and who the Big XXII will add. Obviously the school or schools that are added to the league, will be added for three reasons. Football, television and potential rivalries. Schools such as Memphis, Cincinnati, Central Florida, East Carolina would be nice additions from a football standpoint but horrible from a football television ratings standpoint. Memphis and Cincinnati would have not chance competing for regional viewing with Alabama, Tennessee, Arkansas, Mississippi, Mississippi State and maybe even Louisville. Central Florida would have no chance for television ratings against Florida, Florida State and Miami. The same goes for East Carolina as they would compete against South Carolina, Clemson, North Carolina and others.
If the Big XXII expands, I would expect them to look to Houston, Rice, SMU, Tulsa or maybe westward or possibly to the east coast. It will boil down to whoever won't have to compete for television ratings with other schools in their region.
