NASHVILLE, Tenn. –** The Titans face the Baltimore Ravens on Sunday at Nissan Stadium.
Here's a look at six things to watch:
**
Mariota's mobility**
The last time fans saw Marcus Mariota, the Titans quarterback was still pretty much a pocket passer, limited because of an injured hamstring. Well, the injury Mariota initially suffered back on October 1 has improved, and coach Mike Mularkey said this week his QB might be 100 percent. Will he run more? Will he take off and leave defenders behind him? Will he look like his old self, throwing on the run? Stay tuned.
Corey Davis
Talk about a welcome sight. Davis, the fifth overall pick of the NFL Draft, hasn't played since Week 2 because of his own hamstring injury. Davis returned to the practice field this week, however, and he had a good week. In Week One against the Raiders, Davis caught six passes for 69 yards, and was targeted a team-high 10 times. Mularkey said Davis won't play 60 snaps, but he's going to make his presence felt when he's out there.
**
Improvements?**
The Titans took an in-depth look at themselves during the bye week, with plans to make improvements. After seven games, the Titans are ranked 31st in the NFL in the red zone, with a TD just 41.2% of the time. On third down, the Titans are currently 27th in the NFL. The Titans have been outscored 37-19 in the first quarter of their first seven games. So, will improvement come immediately?
Pressure Flacco
Ravens quarterback Joe Flacco was knocked out of last Thursday's game against Miami with a concussion, but he returned to practice this week and is good to go for Sunday. Flacco has been inconsistent this season, and sometimes downright shaky. The Titans want to generate pressure while forcing him into mistakes. And that reminds me: What does Kevin Byard do for an encore after his 3-INT performance the last time out?

Homecoming**
Roughly 80 former Titans are scheduled to take part in Homecoming festivities at the half, including quarterback Vince Young, receiver Kevin Dyson, safety Blaine Bishop, linebacker Keith Bulluck, receiver Derrick Mason, tackle Brad Hopkins, tight end Frank Wycheck, cornerback Samari Rolle, receiver Nate Washington, safety Lance Schulters and running back LenDale White. It will be fun to see them, and the response from fans.
Steve McNair's sons
A really special moment will take place before the game, when Steve McNair's sons -- Tyler and Trent -- will serve as the Honorary 12th Titans. Each home game at midfield, the 12th Titan plants a sword into the ground before kickoff. Tyler said he'll probably let Trent do the honors since he's especially excited, but Tyler sounded pretty fired up himself. Tyler McNair said the moment should bring a smile to his face. "My dad will definitely be on my mind, but I know his spirit will be there, and it will be a positive outlook," Tyler said. "I know he'll be smiling down from heaven, because he'll be so excited to see us do that."
