Professional career
In March 2016, Bosa was projected to be a top 10 pick in the 2016 NFL Draft by NFL analyst Daniel Jeremiah. Bosa received an invitation to the NFL combine as a top prospect in the upcoming draft. He completed all of the required combine drills and also participated in positional drills. Bosa met and interviewed with 13 NFL teams at the combine, including the Baltimore Ravens, New Orleans Saints, Dallas Cowboys, Cleveland Browns, and Tennessee Titans. His overall performance at the combine was thought by scouts to be impressive. Bosa was drafted in the first round with the third overall selection by the San Diego Chargers. He was the first of five Ohio State players to be drafted in the first round of the 2016 NFL Draft, followed by Ezekiel Elliott, Eli Apple, Taylor Decker, and Darron Lee. When he remained the last unsigned draft pick of his class due to contractual disputes with the team, Bosa's mother stated "I wish we pulled an Eli Manning on draft day", referring to the 2004 NFL Draft in which Manning, a highly touted prospect who was projected to get selected first overall by the Chargers, refused to play for San Diego and forced a draft-day trade to the New York Giants. On August 24, 2016, the Chargers issued a press release stating that they had offered Bosa an initial signing bonus payment that was larger than any rookie has received in the last two NFL drafts, which was more money in 2016 than any rookie in his draft class except Philadelphia Eagles quarterback Carson Wentz. On August 29, 2016, Bosa signed a four-year contract with the team, ending the dispute.
