GAINESVILLE, Fla. €" In the last two years, Tim Tebow and Percy Harvin have directly collaborated on more than 200 plays and close to 3,000 yards of high-wire-act offense.

That doesn't mean Tebow has a simple formula for Harvin's madness. After all, this time Tebow is certain of one thing €" Harvin will probably score this Saturday against The Citadel in the Swamp.

As to how, when and from where on the field, that's all part of Harvin's mystique as one of the greatest Gators offensive weapons of all time.

"With a guy like Percy Harvin, when you say he has three touches or five touches in a game, you want to increase that to eight and 10 touches a game, but also you don't want everybody to be keying on him and him double-covered and still try to force him the ball," Tebow said.

Tough call. It's one that offensive coordinator Dan Mullen must make every game while worrying about getting the ball to all the other playmakers on the Florida (9-1, 7-1 SEC) offense.

It's been three years since Harvin arrived on campus, and it's still difficult to figure out a player who refuses to be defined on the field.

Against South Carolina on Saturday, he did his damage as a running back with two counterruns to the left side for 26- and 80-yard touchdowns.

Against LSU on Oct. 11, Harvin did almost all his damage as a receiver with 112 yards and two scores while rushing for 13 yards on two carries.

Then there's the miraculous Kentucky game, when Harvin pretty much served as a decoy with three touches €" twice as a running back, once as a receiver. He still scored two touchdowns.

Pretty soon he'll sell popcorn in the Swamp stands while running drag routes.

Harvin can barely define himself. He's referred to himself as a wide receiver and a running back at different times this year.

These days, he doesn't mind the ambiguity.

"I'm whatever the team needs me to play €" receiver, running back, it doesn't matter," Harvin said after the South Carolina game.

Arguably the country's best running back/wide receiver combination player, he has had the big-yardage season (1,622 total in 2007) and the big touchdown year (14 in nine games this year), yet it's difficult to tell when he'll rack up the biggest numbers.

It's obvious Harvin has no problem scoring. His streak of 12 straight games with a score is tied for the nation's longest with Texas Tech receiver Michael Crabtree. With 14 scores on 85 plays from scrimmage, Harvin averages a touchdown every sixth touch.
