The conventional wisdom is that Florida jumped Michigan in the human aspect of the BCS because voters didn't want to see a rematch. This makes sense.
However, if that's the case, then why did voters in the AP poll also move Florida ahead of Michigan, with the knowledge that what they did would have no effect on who would play in the national championship game?
Either Florida was legitimately impressive enough in the two weeks that they played and Michigan didn't, or the lobbying by Urban Meyer, Gary Danielson, et al was enough to convince voters that maybe Florida was in fact the #2 team in the country, rather than Michigan.
Some of the explanations that voters in the Harris poll gave for their votes (lol h8 rematch lol) would seem to nullify this argument, but again, AP voters vote with knowledge that they have no effects on the BCS.
For a more accurate picture of WHY and HOW the tides turned in favor of Florida, it would be so much better to have the second-to-last week votes, rather than just the final week, for both Harris and Coaches Poll voters. Obviously enough people had Michigan ahead in the second to last week, but switched for the final poll only. Knowing which voters switched would be much more enlightening as to the motivations.
A case in point would be someone like Ron Zook. Did he have Florida ahead of Michigan in the penultimate coaches poll, and switch his vote to avoid a rematch (which would be retarded because it costs the conference, and therefore his school, money, but judging by his in-game coaching over the years, I wouldn't be surprised if he actually was mentally handicapped), or did he have Florida ahead both weeks because of his allegiance to his ex-players.
Just throwing some thoughts out there. Of course, the AP vote was much closer than either the Hrris or Coaches Polls the last two weeks (3 points as opposed to 38 and 26 points, respectively), but there still must be some sort of explanation.
