So here's the thing, what Bulpett writes is broadly true of literally every star player on a bad team with 2 years (or less) left on their contract. They all could, conceivably, decide to ask out. NBA personnel people broadly speculate about whether they will all the time, its literally been done constantly with Beal for a year and a half. That's just kind of how the NBA works.
Is Bulpett getting this directly from Brown himself or his people? Or is he just hearing from people looking at the situation and speculating that it could happen based on the circumstances?
The first thing would be news, the second thing isn't. Now that doesn't mean we don't post it, obviously, because this is a forum for discussing basketball. But it makes a pretty large difference in how much it matters.
In this case the "sources" are informed speculation, buts that not really news. Its no different than all those stories about "rival front offices" speculating that brown may be available.
