Who said Tebow couldn't play?

What fuels Denver Broncos quarterback Tim Tebow?

Well, besides using any type of criticism as a form of motivation, the former Heisman Trophy-winning Florida Gators quarterback relies on FRS Healthy Energy drink, at least according to his recent commercial.

FRS is believed to be the only sports drink that uses Quercetin, a natural antioxidant originally used to give energy to cancer patients, as its main ingredient. Cancer survivor Lance Armstrong and Los Angeles Lakers guard Derek Fisher also endorse the product. Tebow surprised many sports marketing analysts when he didn't ink a deal with Gatorade, which was invented at his alma mater.

I'm sure many of you first viewed this ad, as I did, during ESPN's well-produced documentary on Tebow that aired earlier this month. More than anything else, the commercial is great for its absurdity. Tebow's been doubted all his life? Really?

Scout.com had Tebow as a five-star prospect coming out of high school, where he finished his career with 9,810 passing yards, 3,186 rushing yards, 95 passing touchdowns and 62 rushing touchdowns.

And then there's the fact that many consider him to be one of college football's greatest players of all time. Of course, we remember that Tebow was the subject of much criticism leading up to last year's draft, where then-Broncos head coach Josh McDaniels shocked many observers by selecting the former Gator late in the first round.

Clearly the ad is playing off of the NFL doubters. The question now is, can Tebow prove those naysayers wrong, too?
