The pitching doesn't surprise me, they stockpiled a lot of young arms at higher levels and it's paying off, despite attrition (Mecias, Biddle, Anderson, et al) enough have risen to the top to sustain a solid rotation, and you still have Appel and Eflin as insurance, and Buchanan as a last resort.
The bullpen doesn't surprise, as some have pointed out for years, RPs tend to be variable, so stockpile a bunch of veterans and let them shake out, Russell, Oberholtz fail, Medina injured, Garcia inconsistent, but Hernandez, Gomez come through, Neris and Araujo are young arms and Bailey may be another veteran on the upswing. Safety in numbers.
The hitting is worse than expected, only Lough has lived up to his past history, Ruf is a huge disappointment, Howard, throw some dirt on him, Bourjas, time to cut bait, etc. Sometimes the bear needs antacids.
