Antonio Cromartie says Adam Gase has NO future with the Jets ... telling TMZ Sports if he were running his old team, he'd fire the guy ASAP for Chiefs OC Eric Bieniemy!!
Cromartie made the bold statement when we got him out in Miami recently ... and he did NOT mince words when it came to his feelings about AG.
As for why he dislikes the guy so much ... Cromartie says the way Gase treated Le'Veon Bell during the season speaks volumes about his capabilities as a head coach.
"We don't give our running back the ball in the second half of a game," Cromartie says. "It just shows you that you're trying to say that you don't need him."
Cromartie says he would have cut bait with Gase after the season ... but says the Jets are stuck with Gase for at least the 2020 season since they didn't move on from him in January.
As for Cromartie's choice for a Gase replacement ... he tells us Andy Reid's offensive coordinator in Kansas City is the perfect man for Gang Green.
"I would go get Eric Bieniemy," Antonio says.
The ex-defensive back also spoke with us about the Rooney Rule ... and says NFL officials are really failing their minority coaching candidates by not revamping the rule.
