Just because the team sucks with PCA in the lineup doesn't mean the team sucks because PCA is in the lineup. If we're all in agreement that he's an obvious net negative offensively right now, that means he must be contributing otherwise to have the end results he has. Do we want to go and figure out the impact he has on the starters' sparking ERAs?
And ultimately I'm fine with PCA going to AAA to figure some stuff out because I think it's good for his long term development. But just stabbing at names because of a hot couple weeks in AAA or because they hit a ball far in a game you watched isn't the way to do it. Just stick Bellinger back in center and figure out some weird Morel/Suzuki/Wisdom/Tauchman 3B/RF/DH platoon. All of those guys are probably going to give you 90-100 wRC offensive production at a minimum, which, as shown above, is far from a guarantee from someone like Canario, without sacrificing a premium defensive position.
