Just from the two games, MIA should be up 2-0. I think it's fair to say MIA is doing more to lose the game themselves than OKC is doing to actually win (stupid turnovers leading to OKC points). But of course none of it matters, it's what the final score reads.
MIA is playing great first-half ball, if only they knew how to play in the second half. You could not ask for a better start than what MIA has already shown in games 1 and 2. Rest of the series is going to be great with the next 3 in Miami!
