In their first possession, Su Wan and Young O'Neal immediately set up a pick and roll on the high right side. The moment Jermaine settled into the screening position, he caused some disruption to the Pistons' defense switching. "Rasheed Wallace," uncertain whether to switch with Prince, hesitated.
If they didn't switch, by the time Prince navigated around him to reposition himself in front of Su Wan, it would definitely be too late.
But just as Su Wan had rounded the screen and had not yet cut inward, Young O'Neal quickly retreated back under the basket.
This move couldn't be called wrong—after all, it wasn't a lackluster "pro forma screening" where he hadn't even stabilized before retreating; he genuinely created an obstacle.
