Jason McCourty (85 tackles, 3 interceptions, 1 TD, 11 passes defensed)
McCourty has long been an underrated player on this Tennessee defense, but it was clear that 2014 was not an effective use of his talents. I expect more from him in year two under Ray Horton. McCourty is certainly capable of that, which warranted his current contract (which will count over $6 million against the cap in 2015). McCourty is a solid tackler underneath and has shown he can make plays on the jump ball. His performance in the Kansas City Chiefs game last season was a thing of beauty. Hopefully with Horton having another year to mold the defense, McCourty can play at that level more often.
Blidi Wreh-Wilson (57 tackles, 1 interception, 10 passes defensed)
The Titans parted ways with Pro-Bowl corner Alterraun Verner after the 2013 season, plugging in an athletic second year man with little to no snaps under his belt. That man, Blidi Wreh-Wilson, certainly has the physical tools to make it as an outside corner in the NFL, but he was burned badly all season long. It was clear early on that he was not ready for such a magnified role, and he found himself frequently targeted by opposing QB's. On top of his on-field troubles, Wreh-Wilson will enter the 2015 training camp with a questionable status due to an injured shoulder that he had repaired, which ended his 2014 season. He's no lock to start again in 2015.
Coty Sensabaugh (47 tackles, 1 sack, 6 passes defensed)
Coty has always been and still is an underrated slot corner. He was part of a battle last offseason with Wreh-Wilson for the vacated CB2 spot. For what it's worth, Coty had the better season, even though he too suffered a string of knocks that sidelined him for a time. Sensabaugh may not have the measurables to match Wreh-Wilson on the outside, but I would argue he can be used there in a pinch if the Titans decide to re-evaluate the position in 2015. The entire Titans secondary was poor-performing last season, but I would expect Coty to be manning the nickel again next season.
Brandon Harris (11 tackles, 3 passes defensed)
After a couple of years in Houston, Harris was an extra man added to the Titans roster. He didn't wow anyone, but he came in and played some solid football when needed, due to Tennessee's multiple injuries at the position. He is a free agent at this point, and there is no indication that the Titans will bring him back to town.
A former 7th round pick that hasn't been able to stick on the active roster. He's practice squad material, and has been for some time.
MarQueston Huff (see safeties)
Long-story short, the Titans need some work at the cornerback position. They were abused outside far too often last year. We'll see if Tennessee decide to address the position in the draft or in free agency.
