NASHVILLE, Tenn. — The 2015 season didn't turn out like fans hoped it would.
But that doesn't mean the season was a lost cause.
Here's a look at some of the highlights – and lowlights – from the year.

Offensive Player of the Year**
Tight end Delanie Walker
Walker led the Titans in receptions (94) and receiving yards (1,088), during a season when he led all NFL tight ends in catches. Walker caught at least six passes in 11 games, and he had at least 60 receiving yards in 10 games despite being the focus of opposing defenses. He also scored a team-high six touchdowns.
Defensive Player of the Year
Defensive Lineman Jurrell Casey
Like Walker on offense, opposing teams regularly focused on slowing down Casey. The big defensive lineman was disruptive anyway. Pro Football Focus graded Casey as the team's best defender during a season when he tied for the team lead with seven sacks and also had 86 tackles, 28 quarterback pressures and 11 tackles for a loss.
Special Teams Player of the Year
Punter Brett Kern
Kern put up some big numbers. He punted the ball 88 times, and his 47.4-yard gross average was second in franchise history. Kern's 40.3-yard net average was third in franchise history, and he had a career-high 34 punts inside the 20, which was third in franchise history. He had only one touchback.

Best rookie**
Quarterback Marcus Mariota
Mariota broke several franchise rookie records in 2015, including most touchdown passes (19), completions (230), passing yards (2,818) and passing attempts (370) while playing in 12 games. He completed three or more touchdown passes on four different occasions during his rookie season. He added plenty of excitement, and reason for optimism moving forward.
Most underrated
Linebacker Avery Williamson
In his second season as a starter, Williamson led the team with 137 tackles. The fifth round pick from 2014 had at least 10 tackles in six games, and at least 15 tackles on two separate occasions. Williamson also produced 3.5 sacks with 13 quarterback pressures, and nine tackles for a loss.

Orakpo, who spent the first part of his career with the Redskins, ended the season with 64 tackles, and he tied for the team lead with seven sacks. He had a team high 37 quarterback pressures, and 12 tackles for a loss. Plus, he helped set a tone on defense.
Most improved
Defensive lineman DaQuan Jones
Jones started the final game of the 2014 season, and then earned the starting spot for 2015 with a solid offseason. The second-year pro did a lot of dirty work in 2015 while producing 67 tackles with 15 quarterback pressures.
Most costly injury
Linebacker Derrick Morgan
Morgan had 4.5 sacks in the first four games, and appeared to be on the verge of a monster year. But he suffered a shoulder injury in the sixth game against the Falcons. Morgan tried to play through the injury, but he wasn't as effective. Eventually, the decision was made to shut him down. The Titans also missed cornerback Jason McCourty, but the loss of Morgan slowed down the pass rush and hurt the secondary.
