Southern Illinois basketball coach Barry Hinson -- who went on a hilarious post-loss rant at a press conference -- just can't seem to keep his foot out of his mouth ... 'cause he just included his daughter in an all new rant on TMZ Sports.
Hinson told us ... his only regret out of the 5-minute long tirade was singling out his starting guard, Marcus Fillyaw by name -- but Hinson doubled down with his attempted apology ... saying Fillyaw was a great guy "you'd really like for your daughter to marry." He should've stopped there.
Hinson continued, "as a matter of fact, my youngest daughter is still out there. I've got her on Craigslist for a husband right now."
Coach was joking -- we're pretty sure -- but yeah ... he should stop including his family in his rants. If you haven't seen it ... Hinson dragged his wife into last night's rant several times.
If coaching doesn't work out ... there's always standup.
