Have two pairs of teams from two conferences ever collaborated on a set of four games, home and away, with four teams, over two years? Each conf. has two home and two away, but each team is limited to a single game against each ooc opponent.
As an example, say you have Michigan and OSU from the Big Ten, and Florida and Alabama from the SEC.
Michigan at Florida
OSU at Alabama
Florida at OSU
Alabama at Michigan
This would give more variety in the non-conference schedule, and somewhat limit the number of road games for all big teams. In the above scenario, Michigan would prob. have the Notre Dame home game in 2010 and the ND road game in 2011. This allows Michigan (and the other three schools) to limit to a single NC road game over a two year period, improves the matchups for fan interest, and allows each team to keep the whole gate for their home game.
There are probably a ton of reasons this is impractical and won't happen, but I am one of the many who wish that Michigan played someone other than MAC teams and the like in the non-conf. games. And while I have enjoyed going to ND games, I'd like to see some games against other worthy ooc opponents.
