I've seen people propose a +1 system for the bowls, which would be somewhere between the current bowl system and the playoffs. If the +1 system would have been in place this year, you know what we'd have gotten? An Alabama-Florida rematch, from the looks of it. (Florida is above Boise State in the polls, and probably in enough computers to stay ahead.) Not much of a fix, in my opinion.
(I assume a +1 system would take the two highest-rated teams in the BCS and match them up after the bowls are done. Maybe if there were a +1, some voters might have thought Boise State deserves a matchup with Alabama and might have voted Boise State higher to get that matchup?)
