Thanks Hammer... That was a good read... I always amazed by the differences between the different advanced metrics and those differences make me pause. I encourage the continued work on Defensive Metrics. I don't think they are cooked yet but I long for the day that they are. I've always been a big defense guy and I think fully cooked metrics will help prove my personal hypothesis of the importance of defense. I agree with the author when he wrote: "There are, I think, two larger points at work here. One is that seemingly trivial details can have large impacts on the results of “advanced” fielding metrics". As for Ben Revere and any questions about his range. I Offer this... Check out the video below: It's one catch... It's a small sample size... Does he get this kind of jump all the time... I don't know... Many claim he doesn't... But if he's capable of doing this once... He's capable of doing it again and (just a guess) maybe 1 or 2 OF'ers could have done this. So if he has jump issues... They are fixable. But for obvious reasons... You can't make Willingham do this ever. www.youtube.com/watch?v=tAts428eqQ0
