I think Kerr would not allow those matchups to take place. It would go something like:
Green on Embiid (and no doubt, Green would be bullied a whole host of times--potentially the greatest challenge of Draymond's career)
KD/Iguodala on Simmons
Klay on Butler
Curry on Redick
Iguodala/KD on Simmons
Sixers could possibly employ the strategy the Rockets are, and have for ages now, in attempting to switch the Warriors' defense, forcing a Curry-defending-Harden (or in this case Curry-on-Simmons) scenario, but the Warriors would doubtless attempt to counter that in as many cases as possible, because unquestionably Simmons driving against Curry would be problematic. Curry's a superb help-defender, only so-so as an on-ball defender. Although Curry's had his moments on-ball, too.
