It's amazing how many of them don't understand how the process works.
Sorry to tell you, but there is a 0% chance of the Canes playing the Gators.
If an SEC team makes the championship game, the Sugar Bowl gets first choice to replace that team. They will take another SEC team, which means that there will only be an SEC team in the Sugar Bowl, and no other. I suppose it could happen if no SEC team makes the championship game, therefore there would be both an SEC team in the Sugar Bowl and an at large team. But even in that scenario, the Orange Bowl would be behind other bowls in getting to pick.
Canes-Iowa could happen. At this point, though, it would mean taking a 1-loss team over an undefeated TCU. I don't see that happening.
Another thing that a lot of people don't know is that if the Rose Bowl loses a team they this year must take a non-BCS team if one is eligible. There are so many people at ESPN who get paid who don't know this.
