You can't reliably stagger two players who start together. Seriously, it amazes me to see people still arguing this after watching this season. Joff is only not getting everygame minutes because he's horrible. Even with that, Pop has had to go to him when everything doesn't go perfectly with his subs utions. Imagine every minute Joff has been getting going to Rudy, then it's much easier to understand what I mean.
I don't understand how you DON'T understand that. Pop is going to play Parker and Mills minutes, and every second one of them is one the court with Murray puts Dejounte at the two. You love conflating what you want to happen with what you believe will happen, and in this case, that's causing you to think Pop is going to bench Patty despite the fact that the team has been perfectly fine with him this season. I understand everyone is annoyed with his deal, and trading him would make sense. But benching him doesn't, and it is likely not even on Pop's long-term radar.
Murray, Parker
Green, Mills
Leonard, Ginobili
Aldridge, Anderson
Gasol, Gay
That's where I see Pop going with his rotation going forward. If Murray stays in the rotation, he's probably going to be playing with Mills to avoid having two smaller guards together at once. He'll try to stagger Pau and LMA, but Gay would be asked to provide minutes behind those guys in cases where both need to miss time. Tony should be the sixth man, so coming in after four or five minutes would make sense. Then Mills would come in a couple of minutes later for Green along with Manu for Kawhi. Then Parker would go out and Murray would come in (and thusly get minutes at the two). Then Green comes in for Manu, Kawhi for Patty, and there you go.
The front court is relatively easy with Gay for Pau, Anderson for Aldridge, Pau for Gay and LMA for Kyle.
