Presnap strategy: Manning > Brees?

Seems like the Broncos have something pretty good going pre snap. Heres what I've observed:

"Omaha" is used to tell the offense that the next command is to snap the ball.

Omaha can be a safety valve for a dwindling play clock to snap the ball quickly and abort presnap checks. (Eliminate delay of game/burning timeouts)

Omaha succeeds a traditional "hut-hut" cadence which, when used in combination with Omaha, is to force defenses to show their coverage.

the combination of Omaha and no Omaha cadence prevents defenses from anticipating the snap on the "hut-hut" cadence, as well as anticipating the snap on the Omaha cadence


I'd be curious to see where they rank in false starts, (if this works- should be near bottom of the league) but I to feel confident saying this is probably one of the several reasons its difficult to get a sack against manning.

Just pointing this out because it seems like we have a lot of presnap problems lately, esp on the road in addition to pressure problems.
