There was little hostility for Devin until he openly called his own team mates out as lazy and then went out and stood around on the court pouting. And then he followed it up with a call out of the fans. It all went down hill from there. There's a difference between being passionate and aggressive towards the other team while taking on and beating some of the best in the nation (see JHo, CP, etc) and calling out your team/fans after a loss, calling out other players on other teams after losing to them, and flexing towards the sky in meaningless games (see Devin).
