NEW YORK (AP) -- Ready for Super Bowl X-L-V-I? Of course, it's Super Bowl 46. But in the NFL tradition, the big game is written out in Roman numerals. It all started with Super Bowl 5 -- that's V. Bob Moore, historian for the Kansas City Chiefs, credits the idea of using Roman numerals to the late Lamar Hunt. Hunt was owner of the Chiefs and one of the godfathers of the modern NFL. Hunt is also credited with coming up with the Super Bowl name. So, why the Roman numerals? Historian Moore says the fancy numbering made the game seem more important.
