I recall reading that Brown had an awful childhood, poor, and possibly homeless at one point as a teenager. I believe he had a father figure assistant coach from CMU that had stayed involved with him until he passed away in 2018 I think, which kinda coincided with him going off the deep end. I believe he arrived at CMU with all of his possessions in a single bag, flat broke, and on his last chance, and that guy took him under his wing. Again, this is all from memory, but I believe Brown has had a troubled life going back a long time.
This is not to excuse anything he has done, he's been an absolute ******* of late, and should be held accountable. Just adding what I recall reading to give some context to his behavior.
