I don't know who Royce is listening to right now, or if he is doing this all on his own, but if he is getting advice, I think he is getting some very bad advice. If he is doing this all on his own, then he is making a huge mistake, imo.
Royce's thing about making his anxiety so public was to draw attention to the problem, and to show (I think) that with proper support and treatment, many people with certain mental illnesses can go forward doing what they want to do with their lives and being successful with them.
To many, what he is doing now just makes him look petty, immature, and selfish, and it is putting out the exact opposite impression of people dealing with anxiety that he wanted to show. After watching this fiasco, what other professional sports team would want to take a chance on any other athlete who comes out in high school or college and admits the he/she deals with a mental illness of some sort? What is happening now is drawing the wrong kind of attention to the problem.
Royce cannot ignore his health problem. However, imo, he needs to "man up" a lot more here, and deal with this problem, and with the team he is contracted to, in a more professional manner. He can't be calling out the Rockets and their managment in tweets or on message boards. He signed a contract. I'm sure there are probably clauses in there that specify expectations of the athlete being in shape, attending practices, publicly commenting on contract disputes and concerns, etc. As a professional, you deal with those things through your agent, and you deal with those things before you sign the contract.
My hunch is that Royce has lost interest in playing in the NBA. The money the first year is guaranteed, although if a player totally fails to live up to his side of the contract, I'm not sure how that would work. If Royce just walks away with the money and never plays, or really even tries to play.......that is really going to make him look bad, imo.
I'm not sure why he does not seem to realize this, but his actions now are doing more damage to his cause of bringing anxiety and other mental illnesses out in the open. Instead of moving forward and advancing the cause, his actions are actually setting it back, imo.
