A quick preview of Thursday night's FedEx BCS National Championship Game between Florida (12-1) and Oklahoma (12-1):
WHAT TO WATCH: The white pants are a dead giveaway. If Oklahoma quarterback Sam Bradford's pants are still white at the end of the game, that's good news for the Sooners and bad news for the Gators. Very few teams have been able to get pressure on Bradford this season, but it's a must if Florida is going to have a chance to slow down this Oklahoma offense. The Gators were second in the SEC this season with 32 sacks. They'd like to have about five or six more on Thursday night and another half dozen times when they send Bradford to the turf.
WHO TO WATCH: It's the question everyone's been asking: How healthy is Percy Harvin? His right ankle injury was a nasty one, and it's probably not realistic to expect him to be 100 percent. But he insists he's close, and Percy Harvin at 80 or 90 percent is still one of the most dynamic players in college football. The Gators will hand it to him, pitch it to him and throw it to him. He finds end zones the way fish find water. There's a reason he's scored touchdowns in the last 14 games in which he's played.
WHY TO WATCH: When was the last time two offenses this explosive were pitted against each other in a game that meant this much? Oklahoma scored more than 60 points in each of its last five games, the first team in the modern era to score 60 or more in five consecutive games. Florida has averaged 49.4 points during its nine-game winning streak. If that's not enough, the last two Heisman Trophy winners will lead the two offenses. Get the calculators ready.
