I assumed he was going pro????
Welcome aboard, Tex! Glad to have you around.
You can have four to a room, but I think they try to have no more than 12 in a suite. So usually, two rooms in the suite are doubles and two rooms are quads for a total of 12. I was lucky enough to live in a room with only eight total, but I was definitely the exception.
While I certainly don't think he looks good at all, "looking like a dumbass" is pretty subjective though. He doesn't think he looks like a dumbass. His peers don't think he looks like a dumbass. Everything he's wearing is expensive designer clothing, so it's not like he's just wearing trash to be rebellious, he paid a lot of money for it and genuinely believes that looks good just like you genuinely believe he does not. The NBA or each individual team could mandate a dress-code for players arriving (like suit and tie or whatever), but as long as they don't, he gets to decide what looks good.
