Sorry to keep harping on the Irish thing, but did you know the horseshoe has seven points on it? (The Colts horseshoe, anyway. Actual shoes for horses depend on the farrier).
Seven is considered a lucky number... Lucky. Luck. I'm telling you, you picked the right team to root for.
Don't hold Boston against the Irish. It's not our fault. We love our green, which makes Indiana a tearmann.
I love it that you chose to root for an underdog instead of the Pats. I don't think it's coincidence that you became a fan around the time Luck got drafted to the Colts. That's providence.
Horseshoe? Luck? Four-leaf clover? Come on. Hoosier Hospitality has roots in Irish fun-lovery. If you're lucky enough to be Irish, you're lucky enough! May the luck of the Irish be with you!
