The 1990 season was DeBerg's best. His 3,444 yards were his third-best single-season career total, and seventh in the league. DeBerg's 96.3 passer rating was a career high (and third in the league), and he finished in the top 10 for yards per attempt (7.8, fourth in the league and his second straight season in the category's top five). He was eighth in the league in passing yards per game and fifth in the league in yards per completion; his previous best was ninth in 1988. DeBerg's 23 touchdown passes ranked sixth, one of his four top-ten seasons. He led the league with a 0.9 interception percentage which included a career-high (and team-record) 223 passes without an interception, one of his three top-ten seasons; the other two were 1979 and 1987.
