Despite the additions of Bernard Pollard and George Wilson in the secondary, the defense still looks very similar to the defense that got shredded for a franchise record 471 points.
That embarrassing total was last in the NFL.
There is nowhere to go but up for this defense. The question is how much will they improve, because they have to show vast improvement to give this team a chance in Pittsburgh.
Another key addition that should help the run defense is the addition of Sammie Lee Hill, and he'll need to make an impact to shutdown a Steelers running game that is stoppable.
The Titans can't afford to struggle against the Steelers running back trio of Isaac Redman, Felix Jones and LaRod Stephens-Howling. It could end up being another long season if the Titans get shredded by these three guys.
Mike Wallace is also no longer in Pittsburgh, so the Titans will need to key in on containing Antonio Brown and Emmanuel Sanders. That's certainly not a tall task with what figures to be a much improved secondary.
Better pass coverage, and no Wallace, should allow the Titans pass rush to put some pressure on Ben Roethlisberger.
It also looks like the Steelers will be without Heath Miller in this game, who had six catches for 67 yards in their meeting last season.
The Titans defense should be able to keep the Steelers below 20 points if they have improved in any way.
