Tim Tebow has yet to write much history in the NFL, but he's already a best-selling author off the field -- at the ripe old age of 23.
Tebow's autobiography, "Through My Eyes," debuted at No. 6 on The New York Times' list of nonfiction best-sellers.
Tebow made news earlier this month when he stopped by "The Daily Show with Jon Stewart" to discuss the book.
Asking Tebow how old he was, Stewart joked with the Broncos passer by suggesting "a lot of people might say you want to wait until you're 24 to write an autobiography."
"I thought 23 was a good age and a good opportunity for me," Tebow said with a smile.
Tebow's progress with the Broncos might be slowed due to the NFL lockout, but he's taken time to work with teammates during informal player-only workouts. He told reporters in May that he's becoming more proficient in dropping back from under center and says he hasn't "taken a rep out of shotgun" this offseason.
Aware that he's under a microscope as he competes with Kyle Orton for Denver's starting quarterback spot, Tebow made it clear he isn't rooting for Orton to slip up, and that the situation will sort itself out.
"You hope he does good, because the better he does, hopefully the better I'll do, and vice versa," said Tebow, who also must outplay veteran Brady Quinn. "I've always relished the opportunity to compete my whole life. I think it will make me better."
It's been a heady period for Tebow, who in April was immortalized by the University of Florida, which honored its three Heisman Trophy winners with life-sized statues outside their stadium. The Gators unveiled bronze likenesses of Steve Spurrier (1966), Danny Wuerffel (1996) and Tebow (2007) during halftime of their spring game.
One of college football's greatest players, Tebow threw for 32 touchdowns and ran for 23 more in 2007, making him the first player to score at least 20 passing and rushing touchdowns in one season. That year, he became the first sophomore to win the Heisman.
