I think the two ways to do a plus one would be option 1, to seed two rotated "bcs" bowls, 1-4, 2-3, than have the winners play in the plus one. Or option 2 would be have the "bcs bowls" revert back to their original tie ins and play around jan 1, rose- pac 10/big 10, sugar- sec, orange-acc, fiesta- big 12 (there could be some shifts in those tie ins + cotton/jerry jones might try to get into play)...than after the bowl games, pick the top 2 teams and have a plus 1. Under option 2, you could run into a few problems with who should be in that plus one though + its almost impossible to have the back to back bowl experience, ie ohio state fans aren't going to the rose bowl in mass, than the next week travel to destination x for a plus one bowl.
