Has the game of football passed by Broncos quarterback Peyton Manning? As a traditional pocket passer in a league where the read-option offense is all the rage, is Manning the last of the dinosaurs? "People have been saying for seven or eight years now that the drop-back quarterback is a thing of the past and the mobile quarterback is the future," said Manning, preparing to crack a joke at his own expense. "And I've always thought to myself: 'Well, this isn't good. I'm going to be out of a job.' " In a brave, new world where stale technology is as worthless as the eight-track player in your grand- father's Oldsmobile, the Broncos gave big money to a 36-year-old quarterback with a creaky neck, after Indianapolis sent Manning to the scrap heap. A risky investment? "I admire the versatility of these young quarterbacks," Manning told me. "But I certainly think there's still a place in the NFL for the drop-back quarterback. Or at least I hope so. I'd like to keep working." Who's hot in the NFL: Colin Kaepernick, Robert Griffin III and Russell Wilson. They are all quarterbacks who run. See Wilson run the offense in Hawaii, after being named an all-star as a rookie. See RG3 run the Redskins back to relevancy. See Kaepernick run all the way to the Super Bowl. Not to incite a riot among Broncomaniacs with a No. 15 jersey stuck in the dark end of the closet, but did Denver get rid of Tim Tebow just as an offensive revolution was beginning? Nobody accuses Denver's John Fox of being a cutting-edge coach. But there's one unavoidable reason Fox is skeptical the same read option used to great success by San Francisco is going to take over and dominate the NFL.
