As batshit crazy as some of Brian's ideas have been, Team Speed Kills (SBNation SEC blog) had a fan post promoted to the front page that not only takes the cake for bat-shit crazy, but it also takes the cake for so crazy it just might work.
He has a 20 team conference by poaching from the ACC and Big 12, with 4 divisions, 3 of which get their own auto-BCS bid. The fourth division is more the "basketball" division with Kentucky, Vandy, South Carolina, Tennessee, and either Notre Dame or Clemson. Yes, we're talking that bat-shit crazy.
Seriously, give it a read. Blows most bat-shit crazy plans out of the water.
