With marquee teams featuring top bill QB's playing in two of the biggest cities in the US, anticipation for Super Bowl XLVI has reached a fever-pitch.

And if Las Vegas is correct, fans may be treated into another nail-biter similar to the New York Giants 17-14 defeat of the New England Patriots in Super Bowl XLII.

The line, with New England now only favored by 3, is the tightest in 30 years, when the San Francisco 49ers were one-point favorites over the Cincinnati Bengals in 1982.

That game, a 26-21 49ers victory that featured Joe Montana at the height of his powers, is widely remembered as one of the greatest Super Bowls in NFL history.

Now, 30 years later, Tom Brady and Eli Manning have a chance to cement their legacies next Sunday and put themselves in truly rarefied air.

Brady will tie John Elway with 5 career starts in the NFL's biggest game, and a win would give him 4 championships, a number only Montana and Bradshaw can match. Manning has the chance to move past his brother and become one of only 10 QB's with multiple Lombardi Trophies under their belt.
