you can win with a staff full of #3's if your bullpen and offense are solid enough. Look at the Royals in '15. Now, take what you said, and walk it out a little further - KC chose an approach and built to it, they had players who fielded well and ran the bases well, with less emphasis on power. They built a dominant bullpen, and an, "acceptable" rotation, but remember, they traded kids for James Shields, and later, for Johnny Cueto (and Ben Zobrist). The core they built got them to within a win of a World Series win, then the push for Cueto and Zobrist got them over the top. Maybe that's what the Brewers have chosen - they build to whatever philosophy it is they've chosen (so far, clearly more OBP and glove, and less reliance on home runs), and they finish the job at the trade deadline. They needed to improve the offense, which they have, and they needed to replace the depth that was lost when Garza got hurt and become ineffective, and more significantly, they have to fill the hole left by Nelson's injury. Chacin in Garza's former spot - ok - but simply patching, and hoping Nelson pitches as though he'd never been hurt for at least half the season seems to counteract what they've done with the offense. I see no way around it, to make the moves for Yelich and Cain make sense for 2018, they need a starting pitcher they don't currently have. Honestly, I'd prefer it to be a younger, probably better pitcher obtained through trade, but I think the need is big enough to force things a bit - if the trade isn't there, I think it's going to be Cobb or Lynn.
