Three weeks ago, when the Warriors announced that they were closing their practice facility to help curtail the spread of the coronavirus, director of team operations Eric Housen’s phone began to light up with requests from players:

You mind grabbing me a couple basketballs? Hey, can you send my workout socks? Could you pick up my orthotics?

In the five days after the NBA suspended play indefinitely, players were still allowed to take turns getting up shots at Chase Center. On that mid-March morning, when six Bay Area counties released shelter-in-place orders for all residents, everyone from Stephen Curry to seldom-used reserves were forced to scramble for workout equipment.

The vast majority of Golden State’s players live in San Francisco apartments, where space is at a premium despite exorbitant rents. With gyms and parks closed, athletes who make millions to play basketball are struggling to find a place to shoot jumpers, a frustrating reality for those who pride themselves on staying sharp and in game shape.

Though the Warriors might not play again this season, they must be ready for any scenario. It’s possible that the NBA could host some regular-season games without fans as a warm-up for the postseason. Even if Golden State (15-50) has been mathematically eliminated from the playoffs, its players would prefer not to show up to games overweight or with a shaky jump shot.

Team trainers have sent players detailed daily workouts, most of which require little more than one’s own body weight. Much of the Warriors’ roster, including Curry and forward Draymond Green, participates in virtual morning rides together on Peloton stationary bikes.

Curry, the only Golden State player whose primary in-season home is outside San Francisco, went more than two weeks without doing what he does better than almost anyone else in human history: shoot a basketball. After his wife, Ayesha, ordered a hoop online, Curry spent roughly five hours assembling it in the driveway of their Atherton mansion.

“I feel like a little 12-year-old kid out there running around,” Curry told the Wall Street Journal. “Simulating game shots in my driveway.”

Many Warriors players don’t have room at their Bay Area homes for a hoop. To remedy this problem and pass the quarantine alongside loved ones, some are sheltering in place at their offseason houses.

Forward Andrew Wiggins is with his girlfriend and young daughter in Huntington, W.Va. Guard Klay Thompson, still recovering from a torn ACL he suffered in June’s NBA Finals, is with his girlfriend in Los Angeles. Guard Mychal Mulder moved in with his parents in Windsor, Ontario.

“I have a court next door, so I’m still able to get up shots every day,” Mulder said. “I’m lucky.”

Others aren’t so fortunate. Center Marquese Chriss, whose San Francisco apartment complex doesn’t have a hoop, asked Housen to drop off a few basketballs so he can work on ball-handling.

Players could buy something like that online or at a store, but the Warriors have advised them to go through Housen for such needs. A Golden State employee since his days as a 12-year-old ball boy, Housen, 46, has fetched everything from dumbbells to shoe inserts to mail.

Before giving the items to a player, he makes sure to disinfect them. Hand sanitizer and a couple of cases of water are included in every delivery.

“We’ve always tried to keep everything really clean,” said Housen, whose responsibilities span booking hotel rooms, washing uniforms and practice gear, transporting luggage, helping furnish the locker-room spread and troubleshooting. “You know, the laundry’s done with anti-bacterial soap and stuff like that.

“But now, it’s more important than ever to disinfect everything. It’s everything you touch.”

Housen has spent hours compiling a massive list of cleaning products known to kill the coronavirus. Whenever the team is free to return to Chase Center, he’ll incorporate them into his daily routine.

If Housen gets a call in coming months telling him to get ready for a game, he’ll be prepared. Everything he’d need to do to pull off a task of that magnitude has been outlined. As Housen put it, “Give me 48 hours of advance notice, and I’ll make sure the guys have everything they require to be ready to roll.”

The bigger question is whether players would be physically ready. Typically, NBA teams have a weeklong training camp and three weeks of exhibitions before the season. That timeline would be significantly condensed should the Warriors play again.

“I told the players, ‘Stay in shape as best as you can on your own,’” head coach Steve Kerr said. “For the most part, that means just working out at home. Not everybody has the capability to do that depending on where they live. It’s very, very difficult.”
