This is the maximum-chaos scenario a couple of friends and I put together last night. The Georgia Tech wins are quite a stretch (and I suppose USC is now too with Barkley out), but not impossible:
Georgia Tech beats Georgia
Oregon State beats Oregon
Florida State beats Florida
Stanford beats UCLA
Clemson beats South Carolina
USC beats Notre Dame
Texas beats Kansas State
Wisconsin beats Nebraska
Miami beats Florida State (were unaware of Miami's decision at the time, so I guess substitute Georgia Tech?)
Georgia beats Alabama
UCLA beats Stanford
Projected BCS Standings (mostly complete guesses on our part):
Georiga 11-2
LSU 10-2
Notre Dame 11-1
Texas A&M 10-2
Alabama 11-2
Florida 11-2
Clemson 11-1
Oregon 10-2
Kansas State 10-2
Oklahoma 10-2
Texas 10-2
Florida State 11-2
Oregon State 10-2
South Carolina 10-3
BCS Championship: Georgia vs LSU
Fiesta Bowl: Oklahoma vs Oregon
Sugar Bowl: Notre Dame vs Kansas State
Orange Bowl: Georgia Tech vs Rutgers
Rose Bowl: UCLA vs Wisconsin
