Lemme throw the playoff proponents a bone. They're spinning their wheels. Right now, there isn't a single idea proposed by anyone so far that addresses the logistical concerns. Only arguments as to why the logistics don't matter, attempts to brush the money aside.
Here's a proposal put forth by SI that actually does take steps at addressing the money issue. I don't think it is perfect - it doesn't solve everything, but then again, nothing will. In the end, all playoffs ideas promise to fix certain problems but end up creating others.
You'd have an 8-team playoff. The teams would be the champions of the six BCS conferences (ACC, Big East, Big Ten, Big 12, Pac-10, SEC), plus the two other most highly ranked teams. The opening round of four games would all be played at home stadiums, and it would take place during this down-time between bowl games. This year, you'd have Wake Forest at Ohio State, Oklahoma at Florida, Louisville at Michigan, and USC at LSU. The losers would each be slotted into BCS bowls (say, USC-Oklahoma in the Fiesta and Louisville-Wake in the Sugar). The winners would play in the two other BCS bowls (say, Michigan-Florida in the Orange and Ohio State-USC in the Rose). There would then be a title game for the two winners.
