No. 53 Beau Brinkley, LS/TE
Brinkley is listed as a tight end, but he'll never take a snap lined up at the end of the offensive line. In his first year as the Titans long snapper, Brinkley proved capable of handling his duties. He stands to remain with the team for the long haul.
No. 52 Quinn Johnson, FB
According to Pro Football Focus (subscription required), Johnson was on the field for a grand total of 257 offensive snaps last season. Averaged throughout the season, Johnson was on the field for just about 16 snaps a game. While most teams have let the position of fullback go extinct, the Titans have held on to it. Expect Quinn to make the roster for one more year after signing a new contract.
No. 51 Khalid Wooten, CB
The Titans defensive back corps has grown awfully crowded over the past couple years in the team's quest to get younger across the board on defense. The new emphasis on press and man coverage skills has added to the team's needs as well. Wooten slides in to provide depth at the position.
No. 50 Robert Johnson, S
Defensive coordinator Jerry Gray played with the idea of starting Johnson last season while moving Griffin to strong safety, but the idea failed miserably. However, Johnson did prove to be a capable backup and should make the team in 2013.
No. 49 Jalen Parmele, RB
Parmele gave the Titans fits during his short time as starter for the rival Jacksonville Jaguars last season. He has a more bruising running style, similar to that of fellow free agent pickup Shonn Greene, and also has experience as a special teams player.
No. 48 Patrick Bailey, LB
While Bailey performed admirably in Collin McCarthy's stead last season, there's too great of a gap in the level of play between the two. The Titans signed Moise Fokou to help remedy the situation and need to relegate Bailey back to what he excels at...special teams coverage.
No. 47 Karl Klug, DE/DT
Klug is a man in transition position-wise. With all the bulking up of the Titans defensive line, Klug will likely see time at defensive end to remain on the roster. Klug proved to be adept at getting to the quarterback in his rookie season, but his slight frame was not suited for run-stopping. The Titans hope his size at end will fit the scheme for both rushing the quarterback and stuffing the run.
No. 46 Brett Kern, P
Kern has proven himself to be one of the league's best punters over the past few seasons. The Titans would like to use him a lot less than the 80-plus punts he's had each of the last two seasons.
