LiAngelo Ball wondered if his stealing incident in China was the reason he didn't get selected in the NBA draft ... saying, "the sh*t I did off the court" might have cost him.
It all went down in the latest episode of the family's Facebook docuseries, "Ball In The Family" ... where cameras caught the middle Ball bro's reaction to not being picked to join Lonzo in the Association.
"I don't know, I guess it's the way I play, I guess," Gelo says of why he thinks he didn't get drafted.
"Or the sh*t I did off the court."
Of course ... Gelo -- along with 2 teammates from UCLA -- were detained in China after stealing several pairs of designer sunglasses and other accessories from multiple stores in Hangzhou.
LiAngelo was suspended from the Bruins indefinitely ... and LaVar eventually pulled him from school to play ball in Lithuania.
Ball joked about the whole ordeal in a Foot Locker ad released just days before the draft ... but it doesn't seem he found it very funny after not being picked.
"Sucks that I didn't get drafted tonight," he said on the show.
Gelo's been hooping in the JBA -- LaVar's startup basketball league -- ever since, waiting to catch on with any NBA team that'd be willing to add him to the roster.
Ball has previously told us he's had interest from NBA teams -- but so far, no one has pulled the trigger on signing him to a deal.
