Kyrie Irving is the most miserable superstar athlete EVER ... so says Charles Barkley, who CAN'T BELIEVE how big of a baby the Celtics PG has been this season.
Kyrie's been super moody the last few weeks as Boston's season has slowly crumbled away from the NBA Championship dreams it had in the preseason.
In fact, while he was walking in to TD Garden last week and photogs were snappin' pics of him, he said loudly, "I’m not gonna miss any of this sh*t when I am done playing."
