It has been 10 years since the St. Louis Rams rode a fast and furious offense that resembled pinball on cleats  the Greatest Show on Turf  to a Super Bowl title.

But that attack, which seemed to come out of nowhere along with quarterback Kurt Warner, was merely prologue to an explosion of innovation that is transforming the N.F.L. Conjured by coaches who borrow from the wide-open college game, new-look offenses have developed into something previously imagined by video gamers in their living rooms.

Nearly every team now has a Wildcat package, the scheme that carried the Miami Dolphins to the playoffs last season by putting players in unexpected positions. And the spread offense floods the field, with receivers stretched from sideline to sideline, to such effect that Warner and the Arizona Cardinals used it about 85 percent of the time on their stunning run to the Super Bowl last season.

On the horizon is the University of Florida’s star quarterback, Tim Tebow, who will enter the draft next year. He could open the door to what was once virtually unthinkable in the N.F.L.: a quarterback with the size and sturdiness of a linebacker who reads the defense and has the freedom to run as often as he passes in the college-style spread-option offense.
