I wouldn't put much into that. Without fieldfx the defensive metrics are all extremely flawed. One way to evaluate that is that last year Angels pitching gave up a 17% line drive rate (one of the best in the league). This year they're giving up 23% (one of the worst). Now I know those metrics attempt to incorporate that, but it's impossible to do so with the general categories they're restricted to with current data collection. It's likely (although currently impossible to prove) that last year Trout faced a lot more easy catches, while this year he's facing very few. That would impact his overall numbers through no fault of his own. Last year his defensive WAR was probably too high, this year waaaaay too low. Just my opinion.
People may not have been quite as happy about it as I remembered, but there's so many deleted posts in the threads that it's impossible to get any kind of accurate sense. There certainly were a good number on both sides.
Here's one of the threads for reference:

My point is that either that's true for basically all teams, or there are likely more teams than not who that happen to more than us. It just seems worse for us subjectively since we follow this team more closely.
The funny thing is, Boni will probably go 3-4 with a home run, double, single, stolen base, and 3 runs scored. Every time we seem to wonder what Gibby is smoking, the players seem to have a good game.
