What is alt passing yards?

Alt passing yards refer to the number of yards gained by a team through additional methods of throwing the ball beyond the traditional quarterback to receiver pass. This can include trick plays such as double-passes, flea-flickers, and other unconventional pass plays. Alt passing yards are not officially recognized by the NFL but are often tracked and reported by sports media outlets. These plays can be especially effective in catching defenses off guard and generating big gains or touchdowns.
