Three things to watch:
Coty Sensabaugh and Blidi Wreh-Wilson remain in competition for roles in the Titans secondary. One will start as a cornerback in base, the other will be part of the nickel package, though the nickel player could line up outside or in the slot. The Titans didn’t see Aaron Rodgers or Drew Brees as they sat out the first two preseason games for Tennessee. Now they'll finally see a big-time quarterback in Matt Ryan throwing to Julio Jones and Roddy White. Those are good challenges all around that should give the Titans something to assess.
The Titans didn’t declare Charlie Whitehurst out during the week, but Whitehurst said we should be able to figure out if he’d dress and play. He could play in the regular season with an injured pinkie finger on his throwing hand. But he hasn’t practiced, and there is no reason to have him taking snaps, offering handoffs, making throws and absorbing contact when he can be healing up. Expect Zach Mettenberger to work as the No. 2 and get plenty of action. Another solid showing will raise the volume for those who want him ahead of Whitehurst on the depth chart, or even ahead of Jake Locker.
Defensive lineman Mike Martin remains out with a hamstring injury. His missed time could hurt him as the Titans sort out a crowded group. Roster locks DaQuan Jones and Al Woods will get snaps at end behind the starters as well as at nose. Karl Klug and Lavar Edwards will have additional opportunities to try to show the Titans they should be on the team with Martin, or even ahead of him.
