Skal looks like a deer in headlights, but on that play, it was on Willie. Skal came out just enough for Willie to get back on Sabonis, so Skal went back to his man at the 3pt line... Willie just got caught ball watching.
Nobody knows what they are supposed to be doing. This is where they have too look deep, ditch the pass first motion complicated off ball screen stuff and simplify. Every time an offensive player has the ball they think "pass" to a fault.
