I think it's a fantastic story and great for college football. They have some kind of wierd, good karma thing going on right now. They are also a pretty good football team. I am pulling for them to make the BCS championship.
However, I have to wonder if their schedule strength and conference affiliation will catch up with them eventually. They have two wins over ranked teams. But the rest of their schedule ain't exactly murderer's row. Even if they win out, there is a chance they will get screwed when the final computer rankings/schedule strength comes out. I have a feeling their hold on the #2 spot will gradually shrink over the next four weeks until someome overtakes them.
Nevertheless......
Go Bulls!
