ENGLEWOOD, COLO. (AP) -- The Denver Broncos still plan on running an option offense.

Only, this version centers on giving Peyton Manning the option of calling anything he wants.

For the second time in six months, offensive coordinator Mike McCoy has to overhaul his playbook to fit the QB under center.

McCoy restructured the offense on the fly last October to better suit Tim Tebow's unique skill set, switching over to the unconventional read-option. Tebow proficiently ran the system, too, leading the Broncos into the playoffs for the first time in six seasons.

But with Tebow a member of the New York Jets and Manning taking over, McCoy has gone back to the drawing board.

Naturally, he's leaning heavily on the opinion of the league's only four-time MVP for this revamped scheme.
