Next summer, Klay Thompson becomes a free agent.

That has a lot of teams interested — they would love to pitch Thompson on how his elite shooting and strong defense would make him the star or their team and lift said team to new levels. Thompson is a big enough talent to have “his own team” if he wants it. Thompson’s free agency also excites fans who want to break up the Warriors juggernaut, this could be the first crack in the armor.

Or not.

At events around the Thompson Family Foundation Golf Tournament this weekend, Thompson reiterated to Mark Medina of the San Jose Mercury News that he wants to remain with the Warriors.

“I’ve said it many times before: I would like to be a Warrior for life,” Thompson told Bay Area News Group before hosting a party at Hotel Vitale as a prelude to his first annual Thompson Family Foundation Golf Tournament on Sunday at TPC Harding Park. “Contract negotiations are way down the line. But I think we all have the same interest. I would love to be here for the rest of my career.”

Would he take a massive discount and sign an extension?

“It’s tough to say,” Thompson said. “I’d definitely be interested. But at the end of the day, I’m going to be a free agent in 2019. Number one on my list would obviously be to stay with the Warriors.”

Thompson’s father Mychel — a former No. 1 pick, a 12-year NBA veteran with a couple of rings, and a current Lakers broadcaster — was more emphatic, speaking to Scott Ostler of the San Francisco Chronicle.

“Oh yeah, you can mark it down,” Mychal Thompson said at a party to kick off the Thompson Family Foundation’s first charity golf tourney. “Klay’s going to retire in the Warriors’ uniform. He’s going to play at Chase Center (the Warriors’ new arena, opening in 2019), and he’s not going to be at Chase Center as a visiting player, he’s going to be a Warrior for the next seven or eight years.”

Two thoughts here.

First, I am not a fan of taking seriously family members comments on players, they often miss the mark. However, there are exceptions, and Mychel Thompson is one of those. Not only has he lived the NBA life, but he and his son are also very close. He’s been a good barometer of what Klay is thinking.

Second, beyond Thompson’s own words, sources from other teams don’t expect Thompson to leave the Warriors. A lot of teams would love to make the pitch, they will place calls and try to get their foot in the door, but nobody really expects him to leave. Thompson is his own guy (he stepped out of his last contract extension talks to play with his dog), he’s not built with the “I have to be the man on my own team” ego that accompanies a lot of star players, what matters most to him is to win and be in a good environment, and he has that in Golden State. Thompson is happy. He’s not likely to sign an extension to stay with the Warriors, that would be financially stupid, but most sources expect him to give the team a discount and stay put.

Which kills the dreams of a lot of fan bases, but it’s the reality.
