The former world champ tried grabbing from announcer Jim Gray to give his two cents on the decision -- Gray wasn't having any of that, though. Adrien did speak his peace, though ... telling Vargas that he clearly beat his ass ... and that his 6ix9ine-looking face proved it.
As we've reported ... Broner and Tekashi have been trading barbs in the week leading up to his fight against Vargas. Broner even threw down a $300k check to counter Tekashi's hypothetical bet that he'd lose this weekend.
Considering how things turned out in the end ... we're guessing he's glad he didn't actually go all in on himself.
