Two analysts out as Purdue reshapes defense
Analysts Daryl Lydon and DeMarcus Acy are no longer with the program as part of a defensive staff restructure, GoldandBlack.com has learned.
Acy worked with the secondary. He was on staff at Purdue under Ryan Walters, working as a recruiting coordinator while also helping out with the cornerbacks. Walters recruited Acy to Missouri when Walters was an assistant in Columbia.
Acy was a standout cornerback at Missouri from 2016-19, when Barry Odom was the Tigers’ head coach. Acy was a three-year starter and team captain in 2019. In 2018, Acy earned second-team All-SEC honors by league coaches. Acy tallied 99 career tackles at Mizzou with seven TFLs and three interceptions.
