I saw that article and I too question the WAR projections for the 2015 position players.
No, it does not make sense to see Castillo rated so hi because he has played about 10 games above A Ball. I guess that metrics used to evaluate him at low levels carry a lot of weight.
The WAR for Pedroia was way too low as well. How do you project a healthy Pedroia who has had , I believe, 5 and 6 WAR seasons recently, so low?
Don't get hung up on not totally understanding WAR. And God help you if you delve into what UZR and UZR150 actually mean.
Of course I have now opened the door to the metric heads to beat me to death for my defiance!!!
