It wasn’t long ago that one of the hottest discussions in the NFL was about running backs no longer being paid.

That changed this offseason as teams rushed to sign free agent running backs, and their investments have paid off handsomely.

The NFL’s three leading rushers all changed teams this offseason: Derrick Henry of the Ravens, Saquon Barkley of the Eagles and Josh Jacobs of the Packers. Former Raven and now Charger JK Dobbins isn’t too far behind the leaders.

When Henry and Dobbins face off in Los Angeles on Monday night, it will not only be a testament to the value of running backs, but also proof that sometimes a change of scenery can be beneficial for everyone involved.

“They are franchise players; That’s what they show, (and) they prove it week in and week out,” Henry said. “These guys are working hard so they can shine during the season and I’m glad they can showcase their talents and have a great year. And hopefully they open doors for the future and other running sports. “Backers who hit (in) free agency also get the opportunity to get paid.”

Due to injuries, Dobbins never had the chance to show his full potential in Baltimore. There was always a part of him that believed he didn’t get enough carries as a rookie, when he led the league in yards per carry. And there was always a part of him that resented the fact that his first serious knee injury occurred in a preseason game.

Still, Dobbins loved Baltimore. Last August, as Dobbins entered his contract year and was healthy again, he said he wanted to be a Raven for life. Just 18 days later, he suffered a torn Achilles tendon in the Ravens’ season opener.

The Ravens turned things around and signed Henry to a two-year deal instead after initial enthusiasm in the free agency scene for younger running backs faded. About a month later, Dobbins signed a one-year, $1.6 million contract — essentially a prove-it deal — with the Chargers.

Henry was a home run in Baltimore, leading the league with 1,185 yards and scoring a touchdown in every game he played. Dobbins was a workhorse in Los Angeles, rushing for 726 yards and eight touchdowns.

“I’m always happy about every running back. JK had a short spell with injuries but he has recovered and is showing his hard work and heart to be back,” said Henry.

“He’s having a great year, he’s doing a great job for them. Hats off to him and the year he has had. I’m excited to see him back out there making plays and doing big things for his team.”
