UZR and UZR/150 are very useful metrics. I personally think using them is very effective. However, the fluctuations from year-to-year change the way that they should be used. When evaluating players, I would advise averaging the total from over a few years rather than just picking out one year.
There are a lot of ways to improve this, which I'm sure someone will manage to do in the upcoming years. There are a lot of extra factors that influence this metric, but they can be worked out. However, as of now, this is the best fielding statistic there is.

3. Do not use UZR per 150 games (UZR/150; found on Fangraphs’ player pages) if at all possible. It’s way too misleading.
I understand UZR. I realize it takes around 3 years of data to accurately evaluate a player. Use the last three years, and you STILL have an above average defender. And there is nothing misleading about using UZR/150 with a guy that has as many innings as OC has played. For a guy that has played 20 innings, then yes, it is very misleading.
