The Warriors learned a lot when Stephen Curry was sidelined 58 games with a broken left hand, but they still have plenty to figure out before entering their longest offseason in eight years.

Many of their most pressing questions deal with rounding out the 2020-21 roster. This week’s mailbag is loaded with queries about who will — and who won’t — be around for next season’s opener. Here are my answers:

@warriors_mac: What is going on with Kevon Looney? Any reason to be concerned for the long-term?

Definitely. Asked Thursday about Looney’s hip issue, Kerr said, “That’s a concern, and we’ll have an update tomorrow.” It’s now Saturday afternoon, and we haven’t received any update other than that Looney won’t play tonight against the 76ers.

Looney was limited to five games as a rookie in 2015-16 to undergo two hip surgeries. His hips haven’t been a big problem in recent years, but there’s always a chance issues resurface. It doesn’t help that Looney’s season has already been derailed by injuries.

Thanks to a neuropathic condition in his body that sidelined him 20 games and left abdominal soreness that sidelined him 18, Looney hasn’t been able to find a rhythm, averaging 3.4 points on 36.7% shooting (7.1% from 3-point range), 3.3 rebounds and one assist. Looney even admitted recently that he’ll need a full offseason to get his body right.

It wouldn’t shock me if the Warriors decided to shut him down for the rest of the season. The bigger concern, however, is what this could mean for him long-term.

If Looney is unable to return to the player Kerr called a “foundational piece” last spring, that’d be a big blow for Golden State. It signed him to a three-year, $15 million deal last summer thinking he’d be the starting center for a championship-caliber team.

@RimRunninRagged: Why did they waste a 10-day contract on Chasson Randle? Another guard to play garbage-time minutes seems superfluous.

That’s an interesting question. To be honest, I’m a little confused about why they went to such great lengths to bring in Randle. I think, more than anything, the timing was just off. They tried to bring over Randle a couple weeks ago, when they only had eight players and no point guards.

By the time Randle reached a settlement with his Chinese Basketball Association team and received a FIBA letter of clearance, he hadn’t played competitively in more than a month. Understandably, he looked a bit rusty in a 12-minute cameo during Tuesday’s win in Denver. Now, with Curry back from his hand injury, there simply aren’t many minutes available for Randle.

It’ll become even tougher for him to get on the floor once Ky Bowman returns from his sprained ankle. At this point, it feels like a long shot that Randle will be brought back on a second 10-day contract. His best chance to prove his worth might come tonight against the 76ers with Bowman still sidelined and Curry out with an illness.

@couchtomato62: Is Ky Bowman a lock for next year’s team? I feel he is fine for a last-place team, but don’t we need some NBA vets?

This might surprise some people, but Bowman is far from a lock for next season’s team. His three-year contract is non-guaranteed for 2020-21 and 2021-22. If the Warriors face a numbers crunch during training camp, they could waive Bowman and be out nothing.

I interviewed Bowman recently for a story, and he went out of his way multiple times to mention that he was playing for a spot on any team — not just the Warriors. That tells me he has an understanding that his place on Golden State’s roster is hardly secure.

After a solid start to the season, Bowman began to regress. His time in the G League appeared to do little in terms of helping him learn how to run an offense. It also doesn’t help that, before he sprained his ankle in a Feb. 27 loss to the Lakers, Bowman had missed 27 of his previous 30 3-pointers.

The Warriors still like Bowman’s energy and athleticism, but I think they see him more as a third point guard rather than someone who could be Curry’s primary backup on a winning team. It doesn’t bode well for Bowman that Golden State has been so insistent in recent weeks about experimenting with Jordan Poole at point guard.

@JasehMorant: If the Warriors were to use their valuable first-round pick this year, what position would they prioritize? And who??

The Warriors subscribe to the philosophy that, when drafting that early, they need to take the best player available — regardless of position. I know a lot has been made of James Wiseman’s potential fit at center, but I don’t think that gives him an advantage in Golden State’s eyes.

Some of the prospects I’ve heard the Warriors are high on are Dayton’s Obi Toppin, Iowa State’s Tyrese Haliburton and Washington’s Jaden McDaniels. If Golden State got the No. 1 pick and didn’t get a trade offer for the selection that it loved, I still think it’d strongly consider taking Georgia’s Anthony Edwards.

@JZalk: Has Marquese Chriss solidified his starting spot at the five next season?

I don’t think anything’s set in stone because a lot can change between now and October. The Warriors could sign a starting-caliber center in free agency, acquire one using their $17 million trade exception or use a top-five pick on Wiseman.

That said, I think Golden State would feel comfortable going into next season with Chriss as its starting center. Over his past 14 games, Chriss is averaging 13.7 points on 58.8% shooting, 8.1 rebounds, two assists and 1.7 blocks.

This is someone who provides almost everything the Warriors want out of their starting center: the ability to run the floor, throw down alley-oops, execute dribble-handoffs with Curry and kick out to open shooters. The big question is whether Chriss can hold his own defensively against some of the league’s best big men.

If he can ease that concern over the final 19 games, he’ll have a good shot at opening next season as the Warriors’ starting center. That’d be quite a feat for a former lottery pick who, after receiving minimal interest in free agency, joined Golden State in September as a non-guaranteed training-camp invitee.

@cmvsal: Can Poole be the primary ball-handler for the second unit next year? He looks like he’s made progress, and he is the best ball-handler when Curry is off the floor.

Depending on how Kerr staggers the rotation, Green might essentially be the second unit’s primary ballhandler next season. However, I think Poole has shown enough as a playmaker to warrant some minutes initiating the offense.

Poole has made it clear he wants to be a point guard, and I think that could be his best role long-term in the NBA. The question is this: Would Golden State feel comfortable going into next season with Poole as Curry’s primary backup? I’m not sure. How he performs over the final 19 games and in summer league will be factored into the Warriors’ backcourt plans.

@byalexcoffey: What are Toscano’s chances of making the roster next season?

Like Bowman, Toscano-Anderson’s three-year contract is non-guaranteed for 2020-21 and 2021-22. If the Warriors need to free up a roster spot for someone, Toscano-Anderson could easily be waived.

However, I think he has a decent shot at making next season’s team as a 14th or 15th man. The Warriors like Toscano-Anderson’s energy, defensive versatility and shot selection. He knows his role and doesn’t try to do too much, which is important for a bench player trying to carve out an NBA niche.

If he’s cut, it might be because the Warriors decide to keep both of their second-round picks in June for salary-cap reasons. The good news for Toscano-Anderson: I think he’s shown enough with Golden State to get an opportunity elsewhere if necessary.
