One of the best stories of the Carolina Panthers training camp and throughout the preseason was the undrafted cornerback from Louisville who kept making a name for himself. Entering the Panthers offseason program as a complete unknown, cornerback Corey Thornton’s road to the 53 man roster had to be earned.
Thornton had the size the Panthers covet with a 6’1 195 lb frame that lends itself way to the physicality the defense requires. When a defensive scheme, like Ejiro Evero’s, that funnels opposing passing games into the short passing attack, cornerbacks who can tackle reliably are imperative to the defense’s success.
From his first preseason game, Thornton showed he wasn’t going to shy away. A highlight WWE-esque tackle made waves on social media for the people who had not been following training camp closely.
Thornton made the roster, but did not get a jersey very often until Week 5 versus the Miami Dolphins when the Panthers needed someone to jump in at nickelback. Despite having little exposure to the role going back to college, the Panthers turned to the Thornton who played 24 snaps with of which coming in coverage. Thornton produced a 73.2 defensive grade by PFF after allowing 1 catch on 3 targets for 8 yards including a pass breakup.
This role wasn’t constant for Thornton, though, as he went back to single digit snaps for almost two full months until back-to-back games in Week 11 and 12. He was on the field for more than half of the team’s defensive snaps until an unfortunate injury in the latter contest would take him out for the rest of the season. Thornton was starting to gain traction as the starting nickel and his physical presence brought more to the defense than the alternatives the Panthers were trying to use such as Chau Smith-Wade.
According to PFF, Thornton was the 4th highest graded undrafted rookie in the NFL in 2025. While his tackling was consistent, his coverage ability was equally impressive. Thornton’s passer rating allowed was the lowest among rookie cornerbacks who were targeted at least 15 times.
If Thornton can get healthy and continue his upward trajectory when the offseason program begins in earnest in July, it wouldn’t be surprising to see Thornton as the teams best option in the slot.
