text: 1970–1977: joining the NFL In 1970, the San Diego Chargers settled into the AFC West division following the NFL merger with the AFL. The years after the merger were difficult for the Chargers. Charlie Waller took over as the head coach, but after finishing 5–6–3, he stepped down, and Gillman returned to the job. Gillman resigned midway through the 1971 season, which finished with six wins and eight losses.
  On May 19, 1971, Ron East was sent to the San Diego Chargers as part of the "Bambi trade" that also involved Pettis Norman and Tony Liscio. In 1972, Duane Thomas and Deacon Jones joined the team, which finished with a 4–9–1 record. In 1973, veteran quarterback Johnny Unitas, formerly from the Baltimore Colts joined the Chargers. Unitas was almost 40 and had chronic injuries. He played three games and then was replaced by the rookie Dan Fouts. The Chargers finished with a 2–11–1 record.
  In the 1974 season, Fouts was named the new the starting quarterback. Don Woods also joined the team. Woods ran for over 1,000 yards but the team had a 5–9 record. However, in 1975, Woods and Fouts underperformed and the team finished 2–12 after facing the possibility of the first-ever 0–14 season until beating the Kansas City Chiefs in their twelfth game.
