It is likely that Kerr stays with his lineup Curry-Klay-Iggy-Dray-Looney, which means Klay and Iggy will guard Dame and Cj, while Curry is guarding Harkless, we'll probably see a lot of Harkless post-ups just like against Jamal Murray. He has to play much better in this series and take advantage of the missmatch, and make the Warriors pay, if he can get Curry in foul trouble, that would be huge. Hopefully Hood will be ready if Harkless is not able to do that
Young Iggy could guard Dame or CJ, this version I honestly don't think he can. Stopping the Blazers Guards is similar to stopping Steph and Klay it's a team scheme, thinking you're gonna stick them 1v1 good luck...
Steph has been getting into foul trouble like crazy; really bad defense. Whoever he is guarding should attack the rim, relentlessly, or post up, and not just take long range jump shots
