Can someone please explain the team efficiency stat to me? Some guy at work starting throwing this around the other day and I was at a loss as to what it was. I have a basic idea of how the player efficiency stat is created, but I am not sure how they get from that to team. If there is a good link to this, or if Evan has already covered it in an article and I missed it, please just throw that out there.
Also, any opinions you have regarding the usefulness of this statistic as a metric would be appreciated.
