Because he's a great player and people are interested in reading about it. And it's not just making things up -- even people around the Warriors think he's leaving, and he has quite intentionally avoided saying anything that would suggest he is staying in Golden State.
The "nobody needs to write about it" stance is silly. People are interested in the topic. They're not making up bullshirt -- he's very likely to leave. Damn near every site has done something on this. So why wouldn't you write about it?
Because the season he's about to play is about to begin.
I often think our posts pass like ships in the night. To be clear: I'm not saying nobody will read it. I'm not saying anyone can't write about it. I'm not talking about the sovereignty of the thing. I'm talking about the need for it. The good of it. The purpose.
There is no need for it. There's a season to play and a title to win. After that, free agency. The presence of such a story is rooted in how the Internet works. It needs to create content every day. Key word: Create. If there's no news, Internet writers have to dream up speculation for news that may or may not ever happen. But there is no need for it. Indeed, it's kind of a waste of time. It's speculative bullshirt. Talk radio nonsense, in digital print.
