I don't see why it cannot be this format...
Regular Season --- 2 non-conference games (against FBS teams only, FCS teams don't count) and 8 conference games. Conference championship games can be played afterwards.
Making the Playoffs Everyone in the Top 25 is guaranteed to make the playoffs. Conference champions who do not make the Top 25 are then placed into the bracket. Afterwards, the bracket is filled by the remaining teams as determined by the polls.
Two week break between end of Regular Season and the Playoffs.
Playoffs - 5 rounds played at 31 different locations (31 games total so no repeats)
Round of 32 locations - Mobile, Jacksonville (FL), Tempe, Boise, Philadelphia,
Kalamazoo, Syracuse, Athens (GA), Chapel Hill (NC), Eugene (OR), Cincinnati, Buffalo, San Diego, Pittsburgh, South Bend (IN), and Madison (WI).
Round of 16 - Tallahasee (FL), Nashville (TN), Indianapolis, Charlotte (NC), Baltimore, East Rutherford (NJ), Honolulu, and Detroit.
Quarterfinals - Tampa Bay, Dallas, Phoenix, and Atlanta.
Semifinals - The Rose Bowl, The Cotton Bowl
National Championship - Washington, DC
Many of the major stadiums would be used, spreading the wealth around. Because every game is an elimination game with prestige, the tickets will be sold out everywhere. Even the small squads get a shot at the playoffs, where they can test their mettle against the powerhouses.
Bracket Selection would be RANDOM...let's see where things stack up. A team has to be willing to play anyone, so why shouldn't it be put to the test?
