On defensive metrics (brief)

I saw this:

Descalso, who at one point was portrayed in the metrics as an elite defender, is now a neutral defender per UZR and a negative with the glove per the +/- system. I'm not here to debate the value or sample size of defensive statistics.

My advice: don't use the stats if you aren't prepared to defend their value or justify their use given the sample size.
