Tennessee Titans running back Chris Johnson isn't expected to be with the Titans much longer due to declining production and an $8 million base salary for next season.

Does Johnson still have something left or is there something else amiss?

NFL Network analyst Terrell Davis expressed a belief that Davis can still play.

However, Davis wonders about his passion for the game after signing a four-year, $53.5 million contract in 2011.

“When I watch film, I don’t see the effort in him,” Davis told the Tennessean. “And I never, ever want to question somebody’s effort. But the tape, it doesn’t lie. And I don’t see the desire I saw when he was Chris Johnson, the no-big-contract Chris Johnson.

“I see times when maybe he is not getting as many yards as he could. He could break a few more tackles, and maybe hit the hole a little harder at times.”
