Yep. The 4 I remember were the Orange, Cotton, Sugar and the Grandaddy of them all, the Rose Bowl. No players sat out of those games, and fans across the country watched those games. The winners of those games were voted N0.1.
Sometimes there was disagreement if the two different Voting bases disagreed, and that was great. It turns out that Oregon was involved with it all going crazy.
When the computer Picked Nebraska to play against Miami, despite everything saying it should have been Oregon, the cast was set. Now, instead of fanbases across the country being interested the whole season, 5 of them now wait until the Invitational, and 5-7 teams can play in a Bowl.
