How confident are the Warriors in their scouting department?

They firmly believe that they will draft a player with the No. 28 pick in Thursday’s NBA draft — a spot often used on prospects who spend most of their careers overseas — who can contribute immediately. With its highest pick since it took Harrison Barnes seventh overall in 2012, Golden State will probably take a rotation-ready wing.

Now, with three days until the draft, The Chronicle is looking at whom the top online mock drafts project the Warriors to select at No. 28:

ESPN Insider, Kevin Pelton

28. Gary Trent, Jr., SG, Duke

As a prospect, Trent is somewhat one-dimensional. Fortunately, that dimension (shooting) is in high demand in the NBA right now. Trent shot 40 percent from 3-point range during his lone season at Duke, and his 88 percent free throw shooting suggests that's no fluke. If Trent can develop the strength to hold up against bigger defenders on switches, it's easy to envision him playing a key role on a good team.

28. Josh Okogie, SG, Georgia Tech

The Warriors are likely to draft a wing here after getting strong results out of Quinn Cook at backup point guard, Patrick McCaw IS a restricted free agent and with Jordan Bell and Damian Jones under contract as young frontcourt pieces. While his game is still rough around the edges, Okogie is the right type of upside play for the Warriors, who won’t require him to do too much and can naturally help rein in his shot selection and let him focus his energy on becoming a stopper. He’s helped himself since the combine and will have a shot to land in the late first round.

28. Khyri Thomas, SG, Creighton

Steady and with great length, Thomas is a low-risk, heady guard who won’t make unforced mistakes and can immediately stretch the floor with his offense.

28. Jacob Evans III, SF, Cincinnati

Evans is a do-everything wing who guards multiple positions, plays tough and consistently makes outside jumpers — evidence being how he shot 39.4 percent from 3-point range in his final two years at Cincinnati while helping the Bearcats earn a No. 2 seed in the NCAA Tournament. He didn't take over games often, it's fair to note. But it's not hard to imagine him flourishing with the Warriors and becoming a useful piece for a championship organization.

28. Grayson Allen, SG, Duke

The Warriors don't exactly need anything. So with Duke sharpshooter Grayson Allen on the board at No. 28, this is a luxury pick. Allen would fit perfectly in Golden State's system as a spot-up 3-point shooter, and he showed himself to be versatile enough to run the point and play off the ball in college. His competitive streak, athleticism and tenacity on defense is a bonus for a team that already has plenty of it.

28. Gary Trent, Jr., SG, Duke

The Warriors normally don't have their pick and end up buying a pick and turning them into a bench contributor. Don't count that out this year as well. At 28, they will probably join the shooting guard party and grab a player that slides like Trent. Son of Shaq of the MAC is being overlooked by many and with the likely departure of Swaggy P, Trent could offer some clutch shooting off the bench.
