1. CB Roger McCreary
McCreary came to the Titans highly-billed: the former Auburn star was drafted by them in the 2nd round, but just barely, going 35th overall in the 2022 NFL Draft. His first season in Tennessee went well, all things considered: he started in all 17 games, had one interception, eight PBUs, and 80 tackles. The analytics weren't quite as bullish on him, though – Pro Football Focus gave him an overall grade in the 60's, based mostly on an NFL Passer Rating of 113 against him and the fact that he committed 10 penalties. It was a good start, but one the areas that needed to be cleaned up were clear.
2023 looked a lot better. His passer rating against dropped into the 80's, he cut the number of penalties in half, and while he played in and started less games than the year before, he managed to end the season with more tackles than his rookie year and added two sacks. He played way more in the slot last year, and with the Titans' addition of former Bengals corner Chidobe Awuzie, that figures to be where he starts in 2024. But nickel packages are basically team's base defense now, and having an above-average guy at that spot in 2024 would do huge things for their defense.
