I think Scal is wrong there. Look what happened to GS when OKC and Cleveland stayed big against them - they killed them on the boards and down low and ultimately showed a critical weakness for them. I think we'd just stay big when they go small, especially with Cousins, because do you think 6'7" Green can really guard Cousins at the 5?
Further, both GS and CLE have about as good of small-ball lineups as you can get:
Curry, Klay, Iggy, KD, and Green for GS;
Irving, Smith, Shump, Lebron, and Love for CLE;
You're not going to "out-small-ball" them, so you might as well hit them where it hurts - down low with size, rebounding, and interior presence.
I still think some combination of Cousins or Butler/George and Noel is a worthwhile and winning formula for us, especially Cousins, who solves about every single issue that we have.
EDIT: I mean, Memphis has beat the Warriors twice now, and it's because they're set up ideally to beat them. They have bigs down low that can rebound and punish their smaller bigs, all while still having good perimeter D to make it difficult for them around the three point line. And we're set up to be just like that. Hell, add Cousins to the group and you have an even better mismatch against them.
