stupid question but....

In America, we each take a great deal of pride in our favorite numbers and colors. He was reciting his personal favorites so as to bless the upcoming play with good luck.

This is a sort of code he calls for changing the play ( or not ) when he comes up to the line and sees how the defense is aligned against the play that was called in the huddle. Hope this helped you. By the way, I miss the early years of ESPN when they carried Australian Rules Football. I loved it.

You guys call it gridiron?! That's frickin awesome! But when the QB's yell something before they get the snap, it's usually a cadence or code for other players. It maybe a route for a specific reciever, or a blocking scheme for the linemen. It just depends on the team. It's different foe every team. Sometimes it's just easier for the QB to call a route when he sees what the defense is doing, or he might want to change it. Hope this helps dude. Gridiron. badass.
