It will be interesting to see if Pop puts Green on Curry and Kawhi on Draymond. It would be similar to what he did against the Thunder in the 2014 WCF. It would be Pop essentially saying, "Okay, you can try doing the 1/4 PnR all you want, but then you're just going to be putting Kawhi on Steph."
There aren't really any good ways to counter that. GS could just go one-on-one, but Curry already knows Green can guard him in iso situations. They could post Draymond up on Leonard, but as we all know, Kawhi's actually a good post defender, and letting Draymond fill up on post attempts is a great way to force the Warriors the slow the pace and lower their efficiency. Running a 1/3 or 1/2 PnR makes it even more obvious that switching is the right choice. A 1/5 is harder to switch, but you don't fear the center roaming nearly as much, even though Bogut is a good passer for a big. So then you just have mismatches in Parker on Klay and LMA/West on Barnes. And so long as the Spurs cover up the three-point line, neither of those guys is going to beat you by themselves.
