Because no one has the slightest idea how to properly quantify defensive value of an individual player.
Counter point
I absolutely love watching baseball, but how many games have I seen Paul DeJong play SS? Maybe two games.
How many games have these FG/BA guys watched? All of them. Therefore, I am more inclined to support what they say about defensive metrics....since its their jobs. Is it perfect? No, but its the best that we have, and its much better than baseball writers giving Rafael Palmiero a Gold Glove award at 1B for playing roughly 40 games there.

I think each team has much better ways of quantifying defensive performance and I would love to see a leak of like the Dodgers or the Astros defensive metrics

Also, statistical mumbo jumbo? Maybe look up some of the stats, and you would see that they are not bad
quote:
Weighted On-Base Average (wOBA) is one of the most important and popular catch-all offensive statistics. It was created by Tom Tango (and notably used in “The Book”) to measure a hitter’s overall offensive value, based on the relative values of each distinct offensive event.
wOBA is based on a simple concept: Not all hits are created equal. Batting average assumes that they are. On-base percentage does too, but does one better by including other ways of reaching base such as walking or being hit by a pitch. Slugging percentage weights hits, but not accurately (Is a double worth twice as much as a single? In short, no) and again ignores other ways of reaching base. On-base plus slugging (OPS) does attempt to combine the different aspects of hitting into one metric, but it assumes that one percentage point of SLG is the same as that of OBP. In reality, a handy estimate is that OBP is around twice as valuable than SLG (the exact ratio is x1.8). In short, OPS is asking the right question, but we can arrive at a more accurate number quite easily.
Simply put, OPS and wOBA will lead you to very similar conclusions in most situations, but if you care about determining how well a player contributes to run scoring, wOBA is a more accurate representation of that contribution. OPS undervalues getting on base relative to hitting for extra bases and does not properly weigh each type of extra base hit.
The wOBA formula for the 2013 season was:
wOBA = (0.690×uBB + 0.722×HBP + 0.888×1B + 1.271×2B + 1.616×3B +
2.101×HR) / (AB + BB – IBB + SF + HBP)
