Pro dancer Val Chmerkovskiy of ABC's "Dancing with the Stars" said there is no clear favorite as the final four competitors -- Green Bay Packers wide receiver Donald Driver, opera singer Katherine Jenkins, TV personality Maria Menounos and Latin heartthrob William Levy -- vie for the Season 14 title.

"There are so many variables that you have no control over," said Chmerkovskiy, who was in New York on Wednesday to promote Dr. Scholl's insoles. "You have the fan votes, you even had mood swings of the judges, so it's not so simple to pick a winner."

The four remaining contestants all have different fan bases, and all have been near the top of the standings all season. "The one thing I thought was the William Levy craze would die down," Chmerkovskiy said, "but it never did!"

And he said, don't be surprised if Driver pulls it off.

"With the long history of athletes and he playing for a blue-collar team and from a blue-collar town, I think that attitude could carry him," said Chmerkovskiy, who partnered with TV host Sherri Shepherd but was eliminated in the third week. "Donald came in and had the right approach. He wasn't arrogant or cocky. And he has an incredible partner. He is the total package."
