For example, it makes the following assumptions:

1. It completely forgets to include the Orange Bowl, although it does assume a winner from that bowl (Georgia), presumably against Cincinnati, which doesn't appear anywhere else (fine assumption, but you would think they would at least include 1 of the 2 most important games, no?)
2. Utah beats Oregon and gets the P12 auto-bid in the Rose Bowl, Oregon falls out of NY6 contention (reasonable assumption and follows Vegas odds)
3. Iowa beats Michigan in the B10 Championship and fills the guaranteed Rose Bowl slot for the B10 (this would be a pretty big upset as Vegas has Michigan at somewhere between -10 and -11)
4. Both Ohio State (Citrus Bowl) and Michigan State (Outback Bowl) drop below BYU; hard to see a scenario where one, let alone both, of those teams fall below BYU
