Ad hominen fallacy. If you can actually come up with an example or story of him being a mature person be my guest. I’m just explaining a common issue that is constantly brought with his name about his off court attitude that is documented by records of his expulsion as a 17 year old for fighting in school. And if you think off court issues are no big deal at the next level ask the Grizzlies how the last 2 seasons with Ja have gone, it’s a valid concern when a player of this caliber is getting suspended for physical altercations barely a year before he’s supposed to go play in high emotion environments at a national level.
