The performance did, however, have bettors up in arms.

Due to a dispute over Christina Aguilera’s 2011 performance, prop bets for the Super Bowl anthem are scored at the conclusion of the first “brave.” Fast forward to Knight’s performance ahead of Super Bowl 53 in Atlanta, and the argument could be made that Knight sang “brave” twice. (On purpose, not erroneously — she’s awesome).

She stretched that “brave” out at the end and may have even started a separate “brave.” That becomes an issue for anyone who placed a bet on the national anthem time. The over/under was set at 110 seconds. Depending on how you time it, the anthem came in at around 118 seconds in entirety.

The definition of that first “brave” though changed the prop completely. If it was stopped at the end of the first “brave,” she hit the under. If time to the end, she easily hit the over.

In 2015, the anthem prop was taken off the board due to suspicious betting. With so much money on the line with this prop, the ultimate decision will be controversial no matter how sportsbooks rule.

How’s that for early controversy?
