The scouting report: how to defend Isaiah
Wall off the paint early
Isaiah takes 31.5% of his shots at the rim and finishes 73.5% there. Build the wall before he turns the corner and force the ball back out rather than meeting him at the cup.
Go under screens, sag into the paint
He is a lower-volume or below-average outside shooter (27% on 100 attempts). You can go under ball screens and sink into the paint to take away the drive and dare him to settle for the jumper.
Stunt and recover, do not fully help
He is a primary creator (7.2 assists a game), so overhelping just feeds his passing. Stunt at the ball and recover to your man rather than leaving a shooter to load up on the drive.
