The thing about a nasty bullpen with iffy command is, as sliderguy points out, that they're gonna have stretches where they're unhittable and stretches where they're walking the park. You can't tell me you'd rather have a bullpen of command artists that in theory induces lots of weak contact, because the ceiling isn't as high on those kinds. We saw those types of mediocre stuff bullpens in the past and everyone called for the FO to go for swing and miss.
Come the playoffs, if the bullpen core gets out of this funk, you have a bunch of relievers who can strike any hitter out regardless of the handedness. That kind of group can get you very far in the playoffs, just takes a little bit of luck going your way the same as any other championship winning squad. Everything has to be clicking at the same time, and when it clicks for guys with good stuff for a week or two they're very tough to hit.
