This goes well beyond a simple case of being egotistical my friend. He is irrational and completely unstable as evidenced by the pattern of behavior he has shown for quite a few years now. From throwing stuff off of a hotel balcony, to his crazy social media rants about his gf's, to his attitude towards his teammates, his referring to himself in the 3rd person, creating new nicknames, his absolutely stupid decisions, how he handles each and everything that comes up, and it has all culminated in the last month or so. He really needs mental help.
