Joseph Anthony Bosa is an American football linebacker for the Los Angeles Chargers of the National Football League (NFL). He played college football at Ohio State and was selected third overall by the Chargers in the 2016 NFL draft, where he was named NFL Defensive Rookie of the Year. Bosa has since been cited as among the best pass rushers in the NFL. He is the son of former NFL player John Bosa and the older brother of current NFL player Nick Bosa.

The 2016 NFL draft was the 81st annual draft of National Football League (NFL) franchises to select newly eligible American football players. As in 2015, the draft took place at the Auditorium Theatre and Grant Park in Chicago. The draft began on Thursday, April 28 with the first round, and ended on Saturday, April 30. The Tennessee Titans, the team with the fewest wins in the NFL for the 2015 season, traded the right to the top pick in the draft to the Los Angeles Rams, the first time the top pick was traded before the draft since 2001 when the San Diego Chargers traded their first pick to the Atlanta Falcons. Ohio State became the second school to have three players drafted in the top ten and to have five players drafted in the first round.
