"22:27."
Assuming Li Wei's touchdown was legal, earning six points, then the Kansas City Chiefs would be able to take the lead by five points, but there would still be the possibility of a comeback in the game.
Opting for a one-point extra point would make the difference six points; choosing a two-point conversion would make it seven points; if the extra point attempt failed, the difference would remain five points.
In other words, no matter what the Kansas City Chiefs tried, the score could still be overturned with just one possession.
Despite the fact that Mariota's "Hail Mary" needed to be seriously questioned, the safest bet was to deny the Tennessee Titans' offense another appearance on the field, ending the game in the hands of the Kansas Chiefs Offense, making the two-point conversion attempt the obvious choice.
Seven seconds.
