Baker Mayfield didn't regret torching Hue Jackson after Sunday's game ... he didn't regret doing it again on Monday ... and he DEFINITELY didn't regret doing it a third time Wednesday.
The QB has been SUPER pissed since his ex-coach bolted for the Bengals -- refusing to hug the guy after their game Sunday and then blasting him as "fake" on social media a day later.
Baker was given a chance to walk back his comments Wednesday ... but dude TRIPLED DOWN on his Hue hate, saying, "I get to have my own opinion on how it transpired and he gets to do what he wants.
