Why Does Peyton Manning Say Omaha?

Denver Broncos legendary quarterback Peyton Manning has dominated in the NFL since being drafted by the Indianapolis Colts in 1998. (Interestingly enough, his Super Bowl opponent, the Panthers, tried to trade up in the draft that year to get him). He has also been a master at dissecting defenses and calling audibles at the line of scrimmage, including his most famous audible call, “Omaha!”

But, what does Omaha mean? According to NFL.com, Manning said at a press conference two year ago that the meaning is somewhat ambiguous (though he probably wants people thinking that):

“I know a lot of people ask what Omaha means,” Manning continued, “and it’s — Omaha is a run play, but it could be a pass play or a play-action pass depending on a couple things: the wind, which way we’re going, the quarter and the jerseys that we’re wearing. So it varies, really, play to play, so, that’s — there’s your answer to that one.

His former wide receiver Reggie Wayne, from Manning’s Indianapolis Colts days, added to, but simplified, the theory in a moment earlier this season:

“Omaha means… he’s going the other way. If it’s a run to the right, if it’s dive right, Omaha is going to be dive left.”

Is Wayne telling the truth, or merely preotecting his old quarterback’s secrets?
