Here are five things I've noticed so far.

2. Russell Westbrook needs more time. The Thunder may still win this series so I don't want to be rash, but Westbrook looks like he hasn't quite fully grasped his role in Oklahoma City yet. He will never be the offensive player that Kevin Durant is because he will never be 6'9"-6'11" and have over a 7-foot wingspan. Don't get me wrong: Westbrook is explosive and a great offensive player. We've seen him do a good job for the majority of this series leading this team and dictating the offense. Maybe coach Scott Brooks has told Westbrook that he should take the most shots each game, but it would seem more logical that the primary shooter should be the 3-time NBA scoring champion, Kevin Durant. Either Westbrook needs more time to grow into his role on this team, or he needs to go.
3. Kevin Durant needs to stay out of foul trouble. Desperately. His presence on the floor alone, whether he's shooting the ball or not, changes the game dramatically. He needs to be on the floor.

5. Some of the role players for each team have stepped up and some have not. Thus, they are cancelling each other out. I really feel that the difference between each of the three games has simply come down to the big three players on each side. Wade disappeared in game 1. Durant found foul trouble in games 2 and 3. Harden scored almost nothing in game 3. Westbrook is hoarding the ball too much late in the game. Miami's big three is more experienced and more consistent (so far), so OKC's three needs to grow up, and fast.
Moving forward, I think it's pretty simple: if Oklahoma City doesn't win tonight, they will not win the series, even if they can take it to seven games. The Miami Heat are just too hungry to give up the title easily, and OKC is not showing enough determination to counteract that right now. One of the beauties of this series, though, is that it has been impossible to predict. All of the plays, even the ones in the first quarter, are making a difference. It's exciting to see two athletic, stellar basketball teams going at it, and I'm excited for the series to continue tonight.
