They’ll get a usable player, or maybe not. They could move into the bottom of the first round, but probably not.

Not to ruin your NBA draft party Thursday night, but the focus of the Pistons under new leader Stan Van Gundy changed the moment they lost the No. 9 pick and were left with one faint hope at No. 38. That pick won’t alter the makeup of the Pistons, and with an underwhelming free-agent list — outside of LeBron James and Carmelo Anthony, of course — a big signing isn’t likely either.

That’s why Van Gundy’s first huge move must be to trade one of his big guys — Josh Smith (preferably) or Greg Monroe (realistically).

Can the Pistons play another season with the painfully cumbersome trio of Smith, Monroe and Andre Drummond? I suppose. Does Van Gundy want to do it? No way.

He admitted the Monroe scenarios have dominated his conversations with owner Tom Gores. As a restricted free agent, Monroe can’t leave on his own, but if he finds an interested team, such as New Orleans, he can nudge Detroit toward a sign-and-trade.

That’s not Van Gundy’s preferred option, but he’d do it. The better, and tougher, option it to deal Smith, who has three years and $40.5 million left on his contract. It sounds impossible after a horrible season in which Smith played out of position and responded by shooting a preposterous 26.4 percent on 3-pointers.

Maybe Van Gundy is a strong enough coach to fix that. But it would require a lot of delicate prodding, such as convincing Smith to come off the bench, and Van Gundy doesn’t strike me as a delicate prodder.
