At one point in his career, Cory Littleton was a starting middle linebacker and one of the best in the league. He made the Pro Bowl in 2018, his first season as a full-time starter with the Rams, and would have over 100 total tackles in 2018 and 2019.
He would leave the Rams and sign with the Las Vegas Raiders in free agency, playing two seasons there and starting 27 games over that stretch. This past offseason he was released by the Raiders but find a home with the Carolina Panthers, however it was primarily as a backup although he did start seven games.
For his career, Littleton has 542 total tackles, 27 tackles for a loss, 9.5 sacks, six interceptions, and 32 passes defended. If the Buffalo Bills were to sign Littleton, it would make sense if the plan was for the team to draft a linebacker in the 2023 NFL Draft. It would give them a veteran to be a leader at the position and a backup option if the rookie was not ready to play right away.
