Here’s what we know about how it all went down with the NBA free agency rush over the last few days — nobody knew anything.

That’s how this works. Everybody guesses, but nobody knows anything … until they do.

Kevin Durant was going to the Knicks. Kevin Durant was going to Lakers. Kevin Durant was staying with the Warriors. He didn’t do any of those.

Kyrie Irving swore he wanted to stay in Boston. It was said that he had made up with Lebron James and was going to join him on the Lakers. Or that it was a certainty he was going to the Knicks. How did any of that work out?

Give the NBA credit: the league has somehow managed to create a news cycle out of a big pile of nothingness. The free agent speculation is a bigger deal that the regular season — granted, that isn’t saying much — but everyone with a microphone or a Twitter account wants to announce as to where these player are going.

And in the end, it really doesn’t matter. Anybody notice how Sacramento did in signing free agents? Or Orlando? That’s because there are so few relevant franchises in a league that seems to have so many relevant players, but really doesn’t.

How many difference makers are there in the entire NBA? Fifteen, maybe? And two of them — Klay Thompson and Durant — will sit out all or most of the 2019-20 season.

And how come the biggest story seems to be all about what one franchise didn’t do as opposed to those who did? First, the Knicks didn’t win the draft lottery, now we have to hear all the wailing and gnashing of teeth about what a death blow it is that they didn’t get Durant and Irving. This is a franchise, by the way, that hasn’t won an NBA title since 1973. Seattle has won more than they don’t even have a team anymore.

But we only have ourselves — and the time of year — to blame. Summer turns non-events into much bigger deals than they should be. If you don’t believe it, then stay tuned for the opening of NFL training camps.
