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.
