Not only is the Super Bowl the biggest event on the sports calendar each year, it's also the biggest betting extravaganza you can find in sports. Hundreds and even thousands of different props will be offered by sportsbooks covering not just the typical angles of passing, rushing and receiving yards or touchdown scorers, but also more exotic offerings such as whether each QB's first pass be complete, will the game be tied after 0-0, will a quarterback catch a pass, and so on. One fun prop not offered by every book is on the event that takes place before the football game: the singing of "The Star Spangled Banner."

Those hoping to get the winning edge before Sunday's 6:30 p.m. ET kickoff at State Farm Stadium in Glendale, Arizona will want to know whether this year's anthem singer, Chris Stapleton, will go Over or Under the line of 2 minutes, 5 seconds.

Stapleton makes it three straight years that a country singer will sing the national anthem, including Eric Church as part of a duet in 2021. That rendition clocked in Over the number at 2 minutes, 17 seconds, while Mickey Guyton blew past the line of 1 minute, 35 seconds last year to clock in at 1 minutes, 52 seconds.
