I've never heard of "Scoop B Robinson" so I have no idea if this is an actual reporter reporting actual quotes or just some joker who writes for a website I've never heard of "Heavy.com" making stuff up for clicks.
What I AM sure of is that the sentiment that the coaching staff and front office bumbled away a potential championship run last season is fair. You had a superstar playing at a superstar level and a bunch of young lottery picks and solid vets who were a quarter away from playing in the NBA finals the previous season.
Did Brown really criticize his coaches and front office? Probably not (or not to the level that's portrayed in the article), but realistically the Celtics tried to have like 9 guys who all thought they were starters on the same team and that's objectively stupid.
Dumber still, even though it was obvious it wouldn't work after the first week of practice, they stubbornly took that same broken team all the way into a second round playoff collapse with no changes.
I don't blame Scoop B Robinson for pretending Jaylen Brown said what is probably something Kyrie Irving actually said in passing. I'm just glad someone said it.
