I hate to be picky, but FSU beat Western Carolina. It was that other school with the old guy coach who's tied for DivI-A all-time wins whose team beat Coastal Carolina. But, there are a lot of teams who can be inserted in your Florida State example of needing to prove themselves against ranked FBS opponents before bowl talk begins - teams that will be hoping that those FCS teams they beat early on pull out at least a .500 season so SOS doesn't sink their national title hopes. As much as I dislike the BCS, the fact that there aren't preseason BCS rankings is something they've got right.
Bill Cowher is secure for at least another season in Pgh., mainly because the Rooney family isn't rash in their decision making and wouldn't fire a man who has by all accounts been hugely successful during his tenure in Pittsburgh.
