Defensive Eff. or Zone Rating
Hey guys so I've been playing for a while and I am a big defensive guy. I was wondering about Team Defensive Efficiency, Individual Defensive efficiency, and ZR rating. So i have a few questions.
Now I was explained the Team Defensive Efficiency is the inverse of your team BABIP or 1-BABIP. And while that is close its not exactly right for me. My team defensive efficiency is .707 (haha i know thats not so great) but my BABIP is .285. So shouldn't my team efficiency be .715?
Also how is Individual defensive efficiency found? I understand ZR. And I've always preferred it. But i don't understand why it is that I often have players with negative ZR and 1.000+ efficiency, or players with +ZR and <1.000 efficiency?
Which one is better, or more accurate in your opinion?
Thanks
