I find all this questioning of plus minus ridiculous, its all about the context. The context is that the plus minus stat CONFIRMS what we all saw with our own eyes. Every game, our starters built a lead in the first quarter that was subsequently pissed away by the bench in the second. From there on they were forced to play catch up. It wasn't just an issue in the Miami series either, it had become a running theme over the course of the season.
I mean, if people can't see this, I honestly question whether they were watching the games. The bench has been an issue, the people who get paid to do this for a living recognized it and have made an attempt to correct this issue. It was the glaring off season need. This isn't even about plus minus, its about using your eyes.
