SAN FRANCISCO >> Steve Kerr considers this Warriors group possibly the deepest team he’s ever coached, and the abundance of NBA-caliber talent showed on Sunday.

Even without Steph Curry, Draymond Green and Andrew Wiggins, the Warriors routed the Pistons 111-93 to improve to 4-0 in the preseason. They never trailed after the opening minutes and led by as much as 26 points.

Brandin Podziemski (12 points, four assists, four rebounds) paced the offense before he left in the third quarter due to an injury, and Trayce Jackson-Davis (12 points, 10 rebounds, three blocks) made an impact on both ends. Six Warriors scored in the double digits.

“Much better tonight than (Friday) night, just getting into our offensive rhythm and creating better shots for each other,” Kerr said postgame. “Thought we played with more energy, more bounce, and those things often go hand-in-hand.”

Golden State stayed hot from behind the arc even without Curry, shooting 18-for-39 (46.2%) from 3. The Warriors’ advantage in that area, as well as at the free-throw line, negated their 21 turnovers.

Curry and Green had a scheduled night off, although Curry’s minor right index finger injury could knock him out of another game out of caution. Wiggins, who has worked back from an illness, is expected to play in Golden State’s final two preseason games, tonight and Friday.

Here are some takeaways from Sunday’s game.

Looney’s going to play >> Some raised their eyebrows when the Warriors fully guaranteed Kevon Looney’s $8 million deal to keep him, but it looks like a prudent decision now.

Looney saw his games played streak snapped last year and fell out of Golden State’s rotation as his productivity slipped. But he spent the summer reimagining his body and conditioning. He took hundreds of 3-pointers a day, and even if his range doesn’t extend to the perimeter for real, he has had a tremendous camp.

In his first-quarter shift, Looney hit a 15-footer off the short roll — he has made a jumper in each preseason game — and was a force on both ends. He finished strong over Isaiah Stewart then stoned Stewart in the post on the other end. He helped key a 17-2 run to close the first quarter.

Looney had eight points, three rebounds, two assists, two steals and a block in 13 minutes. If he produced that exact stat-line consistently, the Warriors would be thrilled.

Slimming down should allow Looney to be more nimble on both ends. With the Warriors committed to playing a big next to Green for the majority of his minutes, Looney is certainly going to be in the mix. That wasn’t the case last year, and didn’t seem obvious heading into training camp.

The Kuminga question >> The starting lineup of Podziesmki, De’Anthony Melton, Moses Moody, Jonathan Kuminga and Jackson-Davis made Kuminga nominally a power forward in a small-ball unit. The Warriors have mostly played Kuminga at small forward this preseason, deploying him in a frontcourt with a pair of non-shooting bigs.

Yet Kuminga played just like a small forward — the position he has known his entire life. The former seventh overall pick drained his first two 3-pointers, continuing a promising trend in the preseason.

Entering Sunday, Kuminga had made seven of his first 13 3-point attempts (53.8%). He even drilled one off-the-dribble pull-up triple at the end of the shot clock on Friday. The Warriors have empowered him to shoot when open, and he has obliged.

“He’s shooting the 3 much more confidently, clearly,” Kerr said of Kuminga. “There’s no hesitation, looks like he’s getting better balance on his shot. And we want the catch-and-shoot when he’s open. The one thing we don’t want is guys to catch and hold.”

Most of the looks Kuminga has taken have been clean opportunities off the catch. Against the Pistons, he hit a stand-still 3-pointer from the wing off a De’Anthony Melton pass and another one off the bounce from the top of the arc, dribbling into an easy one when his defender sagged off. Early in the third quarter, Kuminga didn’t hesitate to fire in transition from the left wing.

Kuminga went 3-for-5 from deep, finishing with 12 points in 23 minutes.

Kuminga certainly still has room to improve. He only snagged two boards, which is a point of emphasis. And even the Pistons, one of the worst teams in the league, had success driving by him. But the perimeter shot looks improved, and that’s the biggest variable for him to play in Golden State’s preferred lineup configurations.
