Not everyone knows who Mickey Guyton is, but she'll be exposed to a massive audience on Sunday when she sings the "Star-Spangled Banner" at the 2022 Super Bowl. Guyton will go on just before the scheduled kickoff at 6:30 p.m. ET at SoFi Stadium in Inglewood, Calif., and her relative anonymity could make placing 2022 Super Bowl National Anthem prop bets a challenge. Nevertheless, there are plenty of 2022 Super Bowl National Anthem props to choose from.

The current Super Bowl National Anthem odds list the over-under at one minute and 35 seconds for Guyton's performance. As for the game itself, the Los Angeles Rams will take on the Cincinnati Bengals in the 2022 Super Bowl, and Guyton's anthem should set the tone for what should be an incredible night, with Snoop Dogg, Dr. Dre, Mary J. Blige and Eminem headlining the 2022 Super Bowl halftime show. Before locking in your 2022 Super Bowl national anthem prop bets, you need to hear what SportsLine NFL expert R.J. White has to say.

CBS Sports' Fantasy and gambling editor, White has delivered consistently on a high volume of picks over the long-term, returning $2,652 to $100 bettors on more than 800 against the spread picks since the start of the 2017 season. It's no surprise, as White has cashed huge twice in the world's most prestigious football handicapping competition, the Las Vegas SuperContest.

Now, White has found an edge in the national anthem prop bet that you have to see over at SportsLine.

Super Bowl 56 national anthem prop bet preview

The 2022 Super Bowl national anthem will be sung by country music star Mickey Guyton. Historically, Super Bowl National Anthem performances have run long, with five of the last seven renditions of the "Star-Spangled Banner" clocking in at over two minutes. However, past performances from Guyton suggest she may not hit the two-minute mark. Guyton's version at the National Memorial Day Concert last year clocked in at under 85 seconds and a performance at the 2015 Country Music Radio Seminar was just over 90.

Using those performances to bet the Super Bowl national anthem over-under might be a little misleading, however. Guyton pre-taped her performance at the Memorial Day concert and sang the 2015 version a capella. She'll be accompanied by live music that she'll have to pace herself with on Sunday. As a result, it wouldn't exactly be out of question for her to hold her notes a little longer.
