In his first season in Arizona, his offensive line allowed 24 sacks, 6th best in the NFL and the fewest given up by the Cardinals since 1978 with 22. Grimm’s offensive line also paved the way for running back Edgerrin James to rush for 1,222 yards, the fifth-best total in team history. The Cardinals' offense finished with the 5th-best passing attack in the NFL and threw for a team-record 32 touchdowns. Grimm remained with the Cardinals until Whisenhunt and the entire offensive staff were fired in December 2012, following a 5–11 season.
