It was an existential threat moment for the Warriors after OKC pummeled them like a pinata. Kerr, Curry, Green, and Butler accepted it for that, and pulled their team along.
They were 1-6 on the road, iirc, 6-6 overall, and facing significantly more road games this month. If they lost these two to SAS, it would have extremely difficult to work back into playoff relevance with an old, injury prone team.
These were must win games for GSW and they played like it, just like in a playoff series. Their deep knowledge, experience, and craft showed up. That the Spurs played them so well with obvious lineup and experience mismatches is encouraging to me.
