Through the rest of the regular season Irons maintained his aggressive, punishing running style and gained over 100 yards rushing in each of his remaining games. He was twice selected SEC Offensive Player of the Week, first following his performance against the Georgia Bulldogs and then again against the Arkansas Razorbacks. For the season he had gained 1293 yards and 13 touchdowns on 256 carries. His 2005 rushing total was the 6th best in Auburn history, placing Irons behind greats like Bo Jackson, Cadillac Williams, and future Cincinnati Bengal teammate, Rudi Johnson. At season's end Irons was a unanimous selection for both the Coaches' All-SEC First-Team and the Associated Press All-SEC First Team.
