J. J. Watt, American football player
Justin James Watt (born March 22, 1989) is an American football defensive end for the Arizona Cardinals of the National Football League (NFL). He played college football at the University of Wisconsin, and was drafted by the Houston Texans in the first round of the 2011 NFL Draft.

Considered to be one of the greatest defensive linemen of all time, Watt received the AP NFL Defensive Player of the Year Award three times in his first five seasons. Although primarily a defensive end, he occasionally shifts to defensive tackle in some situations. He has also taken snaps on offense, catching three touchdown passes during the 2014 season. He holds the Texans' franchise records for both sacks and forced fumbles. In 2017, Sports Illustrated named Watt its Sportsman of the Year.
