Simmons was not invited to the NFL scouting combine this year due to past violence issues but was still taken in the first round.
In 2016, Simmons was captured on video assaulting a woman. He apologized for his actions and took full responsibility for not "thinking" about what he was doing. Simmons was suspended by the Bulldogs for one game as a result. Simmons finished his career at Mississippi State with 163 tackles, including 33 for a loss, and seven sacks.
The Titans finished at 9–7 for the third straight season in 2018, failing to qualify for the postseason after losing a Week 17 win-and-in contest against the Colts. Simmons will not be immediately available to Tennessee, however, after tearing his ACL in February while working out before the draft.
