They didn't start choking until they were up 3-1. They are at their best when they are the underdog. When Westbrook went down, KD won MVP. When KD went down, Westbrook evolved into a triple double machine. When all odds are against them, they played the best basketball of their career to beat the Spurs and humiliate the Warriors. Home court does not matter. Game 7 in California doesn't matter. The only thing that matters is who wants it more. The Thunder still have a chance, in fact, I would even go as far as saying this is the best position they can be in: as the underdog.
