The Lakers were blown out at home by the Milwaukee Bucks for the game preceding today's game between the Lakers and Heat. That should definitely help their performance against Miami, as it will refocus them. I'll watch the game today but it should definitely have had a positive effect overall.
We'll see the results shortly.
The other side of the coin is that today the Lakers will give their best effort, and I'm sure the Heat will too. So taking into account home court advantage, it should be a good indicator of where each team is relative to each other.
If the Lakers lose today, thats a bad sign.
The match-ups will be interesting
