Kerr doesn't like NBA's new coach's challenge

Golden State Warriors head coach Steve Kerr won a coach's challenge during Thursday night's preseason action versus the Minnesota Timberwolves when referees overturned an out-of-bounds call against his club.

But despite benefiting from the decision, the 54-year-old thinks the game is better off without the new rule.

"I don't like the rule," Kerr told reporters, including ESPN's Nick Friedell. "I don't like replay at all. I think replay should be limited to the buzzer-beater at the end of every quarter if you want to review them, a buzzer-beater, that's fine. I don't like the review."

The challenge system has been experimented with in the G League over the past two seasons and was given a trial run during summer league play. The NBA will adopt it on a one-year trial basis for the 2019-20 campaign.

In addition to out-of-bounds violations, coaches can challenge fouls, goaltending, and basket interference. Coaches must call a timeout immediately following the play in question in order to formally make a challenge.

Each coach will be permitted one challenge per game and won't receive another even if the first is successful. A challenge won't be granted if a team has no timeouts remaining.

"They send us the rules and we've watched the videotape, so it seemed like something I might as well try just to feel it (out)," Kerr said. "But you have to call a timeout in order to challenge, so it seems like what you have to do is make sure you're not wasting a timeout on a play that's not worth challenging.

"So that's going to be a big factor - if it's your timeout anyway coming up, if there's a mandatory coming up that's yours or if you're on the bad end of a run and you see something that's questionable, you might as well take the timeout and review it. And that way there's no harm done if you don't get the call."
