ACC 
The league loses a few of its top teams to the SEC, mostly because of geography, and it raids the Big East cupboard yet again while also bringing in some choice Conference USAers. In this case, what I think will happen matches up with what will probably end up happening. 
Add: Cincinnati, East Carolina, Pitt, Louisville, UCF, South Florida, Syracuse, West Virginia 
Lose: Clemson, Florida State, Georgia Tech, Miami 
The 2015 ACC Will Probably Be 
 Atlantic: Boston College, Cincinnati, East Carolina, Maryland, Pitt, Louisville, Syracuse, West Virginia 
Coastal: Duke, North Carolina, NC State, South Florida, UCF, Virginia, Virginia Tech, Wake Forest 
Big East 
It disbands as a major football conference and concentrates on basketball. 
Big Ten 
It all depends on Texas. If the Longhorns go to the Pac 10, then the Big Ten ends up raiding the Big East for more than just Rutgers (probably Connecticut). The league has its three teams set up in Nebraska, Missouri, and Rutgers (no matter what the Big 12 guys are saying), and itll do a dance with Notre Dame before finally reeling in the big prize five years from now. Personally, I think Texas ends up in the Big Ten, but lets say that doesnt happen 
 for now. 
Add: Connecticut, Missouri, Nebraska, Notre Dame, Rutgers 
Lose: No one
 
The 2015 Big Ten Will Probably Be 
 
East: Connecticut, Indiana, Michigan, Michigan State, Ohio State, Penn State, Purdue, Rutgers 
West: Illinois, Iowa, Minnesota, Missouri, Nebraska, Northwestern, Notre Dame, Wisconsin 
Big 12 
The league will try to stop the bleeding by picking up all the top Mountain West and Conference USA teams, and while it wont be anywhere near as good a conference, itll still be competitively interesting. 
Add: Boise State, BYU, Colorado State, Fresno State, Houston, Nevada, San Diego State, SMU, Southern Miss, TCU, UNLV, Utah 
Lose: Colorado, Missouri, Nebraska, Oklahoma, Oklahoma State, Texas, Texas A&M, Texas Tech 
The 2015 Big 12 Will Probably Be 
 
North: Boise State, Colorado State, Fresno State, Kansas, Kansas State, Iowa State, Nevada, UNLV 
South:  Baylor, BYU, Houston, San Diego State, SMU, Southern Miss, TCU, Utah 
Pac 10 
The league isnt thinking small as it realizes that raiding the Mountain West wont do anything for the TV dollars. Again, lets assume the Big 12 South (sans Baylor) is making the move. I dont think the Pac 10 is getting Texas, and it might make a push then for Kansas for the basketball program. USC would end up being on the other side of Texas division-wise. 
Add: Colorado, Oklahoma, Oklahoma State, Texas, Texas A&M, Texas Tech 
Drop: No one 
The 2015 Pac 10 Will Probably Be 
 
North: California, Colorado, Oregon, Oregon State, Stanford, USC, Washington, Washington State 
South: Arizona, Arizona State, Oklahoma, Oklahoma State, Texas, Texas A&M, Texas Tech, UCLA 
SEC 
The SEC will easily take over the programs that make geographic and regional sense, and all of a sudden, ESPN will have gotten a bargain for its billion-dollar TV deal. While the newly formed league wouldnt have the reach of the Big Ten, it would take on a life unto its own and would be a cash cow for all the members and the networks. 
Add: Clemson, Florida State, Georgia Tech, Miami 
Lose: No one 
The 2015 SEC Will Probably Be 
 
East: Clemson, Florida, Georgia, Georgia Tech, Kentucky, South Carolina, Tennessee, Vanderbilt 
West: Alabama, Arkansas, Auburn, Florida State, LSU, Miami, Mississippi, Mississippi State 
Conference USA, Mountain West, WAC 
Trying to piece something together, the three leagues form a new 16-team conference that could put together a nice, midrange TV package. 
The 2015 Mish Mosh League Will Probably Be 
 
East: Air Force, Idaho, Louisiana Tech, Memphis, Rice, Tulane, Wyoming 
West: Hawaii, New Mexico, New Mexico State, San Jose State, Tulsa, Utah State, UTEP 
MAC 
The league stays the same but welcomes home Marshall while bringing aboard Army and Navy to create a 16-team league.
 
The 2015 MAC Will Probably Be 
 
East: Akron, Army, Buffalo, Marshall, Miami Univ., Navy, Ohio, Temple 
West: Ball State, Bowling Green, Central Michigan, Eastern Michigan, Kent State, Northern Illinois, Toledo, Western Michigan 
Sun Belt 
The league adds UAB to form a natural geographic rivalry with several nearby programs. 
The 2015 Sun Belt Will Probably Be 
 
Arkansas State, Florida Atlantic, FIU, Louisiana, Middle Tennessee, North Texas, Troy, UAB, ULM, Western Kentucky
