Chris Johnson says he's straight-up jealous of Derrick Henry ... telling TMZ Sports the Titans running back is going to FEAST in 2021 after the Julio Jones trade!!
"I wish I could've played there when we had that GM," the former Tennessee halfback said. "They doing what they got to do to win games."
As for why CJ2K sees Henry exploding ... Johnson says it's simple -- with Julio and A.J. Brown now on the outsides, Chris says it's not possible for defenses to just key in on Derrick.
