One of the major storylines in the NFL this season will be whether the 30-year-old Derrick Henry can continue to play at a high level. He was one of the Baltimore Ravens’ key offseason additions, and if he continues to be one of the NFL’s top running backs, Baltimore is going to be scary this season.

At least one veteran NFL coach believes Henry will remain a menace.

“He’s a warrior,” they told ESPN’s Jeremy Fowler on Monday. “Just keeps himself in such good physical conditioning with offseason workouts. I don’t see him slowing down over the next two years. He’s a volume back with great size, breaks tackles, has deceptive speed and no one’s really catching him if he gets going. I don’t think he’s lost a step.”

No running back in football has been as consistent as Henry over the past six seasons. In that period he’s rushed for over 1,000 yards five times, over 2,000 yards once and has reached double-digit rushing touchdowns six straight times.

One note of potential concern, however, is his massive workload during that time. He’s logged at least 230 touches in six straight seasons, including three campaigns with over 300 carries.

Many running backs tend to break down as they near 30, especially with that sort of workload. But Henry is a unique physical specimen—perhaps he’ll be able to stave off losing a step for another season or two as well.
