William Gay (born January 1, 1985) is an American football coach and former cornerback, who is the current defensive backs coach for the Missouri State Bears. He played college football for the University of Louisville for head coach Bobby Petrino from 2003 to 2006 before being drafted by the Pittsburgh Steelers in the fifth round of the 2007 NFL Draft. He would later win Super Bowl XLIII with the team over the Arizona Cardinals.
Gay signed with the Cardinals prior to the 2012 NFL season before returning to Pittsburgh the following year.
Gay attended James S. Rickards High School in Tallahassee, Florida, where he played quarterback, wide receiver and safety for the Raiders. He racked up over 1,200 all-purpose yards and 12 touchdowns as a junior. He notched 1,035 yards and seven scores passing, 1,237 yards and 11 scores receiving and 82 tackles, 14 pass breakups and nine interceptions at defensive back as a senior when he was named team co-MVP and earned first team All-Big Bend Area honors.
Gay was also a standout in track & field. In 2002, he placed 8th in the 200-meter dash with a time of 22.61 seconds at the Capital City Classic. At the FHSAA Region 3A he took 3rd in the long jump (7.07m or 23 feet, 2 inches) and 14th in the 400-meter dash (51.0 seconds). He was also clocked at 4.4 in the 40-yard dash.
Gay played college football at the University of Louisville where he played in 46 games recording 134 tackles. Gay is also somewhat notable for being offside as a defender on a field goal kick attempt in the final minute of Louisville’s game against Rutgers in 2006. Although the kick was unsuccessful, a penalty was called against Louisville that provided the kicker with a second attempt. This one was successful. As a result, Louisville experienced their only loss of the season, effectively ending their bid for a National Championship game berth.
