For the average fan I think one of the issues with UZR stats is the evidence factor. If a fielder is charged with an error, it's easy to track down and watch the specific play he made the error on. But if there's a ball he didn't get to that he should have, it's much harder to find the evidence.
One problem I have with UZR is there is no way to know if the two defenders would have been positioned the same for that particular play.
It is like when a star player goes down, and people blame the loss on having the back up in.
Even is the star player is a .325 hitter, there's no way to tell if he would have gotten a hit when the back up didn't.
The player with the better UZR may have been leaning the other way on a certain play, might have been positioned differently due to the capabilities of players around him, etc.
Too many variables.
Don't quote me on this, but i am farily certain that UZR not only takes into account the positioning of a player but also the distance traveled to make the play
I believe it does not. I think each position defnds an overlaid zone, and the player is credited for all plays in zone, penalized for every in zone play with no play made. And awarded bonuz for plays outside the zone.
The lack of accomodation for playeposition is a criticism I have heard about using UZR for outfielders...si
