The difference between the games in OKC and LA were like night and day. LA played hard defense all night and Westbrook couldn't abuse Kobe the way he did Fisher.
Charles Barkley said something obvious that needed to be said: LA doesn't have to win in OKC. All they need to do is hold home court which they have. OKC looked very tentative against LA's pressure and they have to learn how to be effective against that.
The only thing you can say about LA is that they didn't come to play in OKC, which is not something a Championship team should do. Still any momentum OKC had from their two home wins is now gone. They have to win there again and force a game seven than go to LA and do it again.
LA is still the better team, they just have to play like they want it and they can close out the series next game.
