No. 3 unexpected signing the Titans can still make: Troy Hill, CB
Cornerback doesn't often come up as a weakness for Tennessee but they could certainly welcome reinforcements to the position, especially in the slot. The Titans had several players handle nickel duties last year but Roger McCreary got the most defensive snaps inside, at 367. However, he also played 662 defense snaps in the boundaries. It would be a good idea to bring in someone else who can line up in the slot, so McCreary can remain outside full-time.
One solid option would be Troy Hill, who's mainly played nickel throughout his career and remains unsigned. An undrafted free agent in 2015, Hill spent a season with the Cincinnati Bengals before joining the Los Angeles Rams in 2016. He latched onto the Cleveland Browns in 2021 but was traded back to Los Angeles last year.
Overall, Hill has appeared in 97 games with 55 starts and has registered eight interceptions (all of them these past five seasons) and 34 passes defensed. He could either become the Titans' primary nickel and/or add depth to a group that has dealt with injuries the last two seasons.
Kristian Fulton, who's slated to start opposite McCreary, dealt with hamstring and groin injuries last year. He ended up sitting out five games and has never started a full season since the Titans made him a second-round pick in the 2020 draft. He's missed a total of 20 contests over the last three years, so it would be a good idea to have a contingency plan in place. Hill would provide just that.
