Miami plays smart on both ends of the court, they have the best player in basketball and a really good big 3, smart role players surrounding them, and some great guys to bring off the bench. It would be stupid to underrate Miami even though the Spurs are playing really well.
Keys to any possible victory:
Defensively, Splitter has to be able to keep Bosh contained, Green has to be able to handle a less-than-100% Wade, and Duncan has to be able to cheat off of Haslem or whoever to back up Leonard when LeBron posts him up or drives. Leonard and Diaw aren't going to be able to stop LeBron even with a double team backing them up, but they have to try to keep him from completely embarrassing them.
Offensively, Parker has to force Miami to choose between him ripping them apart on penetration and hitting the open 3 when they bring enough help to stop him. Duncan and Splitter have to take their size advantage over Bosh and Haslem and really pound them. We have two strong big men, and at least one of them should always have an offensive mismatch in the post -- if we can't make Miami regret their lack of size, we can't win this series. If Manu can bring it this series, that will also give us a great opportunity. I'm not sure how much he has left in the tank right now, but if he has anything, his unpredictability is a huge asset against a Miami defense that is so fundamentally sound.
Miami's going to win at least one game this series that's going to cause a bunch of the doubters to quit on this team -- like Golden State, only worse.
As I mentioned above, I thin the Spurs have a lot of matchups we can take advantage of, but even with that, we're playing an incredible team that is sure to be the favorite going in. This series has a chance to be f'ing legendary. We need to win one in Miami, two of three at home, and one of the last 2 in Miami to get it done. Spurs in 7.
