Calloway started 11 of 12 games as a sophomore, leading the team with 54 catches for 721 yards and three touchdowns, engaging his speed and elusiveness and also showing the ability to stiff-arm defensive backs in the open field. He was also the primary punt returner (26 att., 218 yards) and returned an onside kick 44 yards for a score. Calloway has had issues off the field, though
He faced a sexual assault trial between his freshman and sophomore year but was cleared of those charges before the 2016 season by admitting during the hearing he was "so stoned" he did not want to have sex with anyone. He was also cited for marijuana possession in May 2017 as a passenger in a car stopped because the driver wasn't wearing his seat belt; he pled no contest to possession of paraphernalia in July 2017. Calloway never played in 2017 because of his involvement in a credit card fraud scheme with other teammates. Instead of looking for reinstatement or a transfer, he decided to declare for the 2018 NFL Draft.
Joining Callaway are DT Taven Bryan, CB Duke Dawson, S Marcell Harris, K Eddy Pinero and Punter Johnny Townsend.
