Several offseason additions — and the continued development of RB Chris Johnson — should make the Titans’ offense more potent this season. That’s the feeling after the Titans completed their offseason workouts.

Johnson, who rushed for 1,228 yards as a rookie, gave the offense a tremendous jolt with his speed as a rookie. This season, the Titans plan to incorporate him even more in the passing game with the goal of allowing him to make plays in space. In a recent interview with PFW, Johnson noted that “a big thing that I have to work on this season is my route running, because there’s a lot that goes into running routes out of the backfield and catching balls out of the backfield.”

The way we hear it, Johnson, who made recent headlines by looking to distance himself from the “Smash and Dash” nickname he shared with LenDale White last season, has earned the respect of the locker room because of his work ethic and production.

One of the pleasant surprises of the workouts was rookie TE Jared Cook, a third-round pick from South Carolina who ran a faster 40-yard dash than anyone at his position at the NFL Scouting Combine. Cook’s speed was on full display in workouts, and we hear that he has a good shot at earning a role in the offense as long as he has a solid training camp. Head coach Jeff Fisher came away impressed with Cook’s ability to learn the offense at a consistent rate throughout the workouts, which can be a challenge for some rookies.

“He appears to be a guy that will go home for a week or two and digest the information, come back and move on,” Fisher said. “Some guys have a tendency to re-learn it; he doesn’t.”

The 6-5, 246-pound Cook could be split out wide, much like San Diego has used Antonio Gates and Baltimore has used Todd Heap in the past.

Also bringing speed to the edges is former Steelers WR Nate Washington, and a source close to the club believes Washington’s ability to stretch the field can only help fellow starting WR Justin Gage, who also has shown an ability to get down the field at times. In addition, first-round pick Kenny Britt, slowed by a hamstring injury in workouts, was a big-play threat at Rutgers.
