Eh. They run a zillion plays so all the stats they put up have to be taken in that context.
Even the points they put up, people forget that the faster they go, the more opportunities it gives the opposing team. They routinely lose time of possession, sometimes by a lot. It puts tremendous pressure on their defense. You can put up 30 points but if you need a lot of extra possessions to do it, it's not as impressive. Especially when you are giving the other team extra chances to do the same thing.
They are the ultimate team where you can't view anything they do in a vacuum.
Points per possession would be a much better indicator of their effectiveness and I don't know but I'd bet it isn't as high as their raw numbers might suggest.
