It's
Bleacher Report because the trade is patently illegal. Leaving out that it's bad and misunderstands sign-and-trades in terms of value, it's impossible to do legally. It's gross that a person paid to write about basketball doesn't know that.
You cannot sign-and-trade using picks made during a draft. No, you also can't discuss it beforehand and just execute it afterward. No, you can't have a wink-wink deal to do the trade and pretend like it wasn't discussed. And no, it's not done all the time and would not be allowed.
The Spurs aren't trading 9 in any deal for a player not under contract after the end of the year. It has not legs, and it's not even a rumor worth discussing. The Spurs would be foolish to trade a ton for ing Ayton when they are the ones paying him a max contract. If this were legal, the Spurs wouldn't be giving Richards, 9 and 38. They'd probably give McDermott, 25 and a future heavily protected pick. The Spurs are not a cap cow for other clubs to make their ends meet. Not for free they aren't.
