After redshirting in 2010 when the team signed Oregon-transfer Jeremiah Masoli, Mackey entered 2011 expected to win the starting quarterback job but was suspended for the season opener. With Ole Miss struggling to find an offensive identity, Mackey was re-inserted back into the starting lineup against Fresno State and started the next five games for the Rebels before getting suspended again prior to the matchup with LSU.
For the year, Mackey completed 49.7% of his passes for 1,112 yards and seven touchdowns against five interceptions. One of Hugh Freeze's earliest decisions was moving Mackey to wide receiver. Mackey struggled running routes and has since been moved to running back, where his speed (reportedly has run in the 4.4s) and elusiveness is expected to help him become an immediate and versatile playmaker for the Rebels.
