Brewer left Oklahoma State in 2011 to join the coaching staff at Ole Miss as their associate head coach, passing game coordinator, and wide receivers coach.[2] He only spent one season with the Rebels before leaving to join the coaching staff at North Carolina as their co-offensive coordinator and wide receivers coach.[3]
Brewer was named the wide receivers coach for the Philadelphia Eagles before the 2018 season.[4][5] A season where they played as the defending Super Bowl champions and finished 9–7, Brewer had his contract terminated by the Eagles as the receiving corps had issues with substitutions among other things.[6]
Brewer was hired to be the wide receivers coach at Louisville in 2019.[7]
