I think they need a body now, basically figure out a way to clone Colin Rea. But I still want an upgrade in talent. Edward Cabrera throws real fast, but he's also 88th in FIP for pitchers with over 40 innings this year. That's a bad third pitcher by league average metrics. Yes, Boyd, Imanaga, and Brown are all better (though Shota has his own problems)....but are we really going to look in the mirror in July and say we're good with, best case scenario, our postseason rotation being Boyd and Shota (again) and then the guy who will almost assuredly be way past his career innings?
My general philosophy towards things is actually probably that we should do that. That this team is good enough to make the playoffs, and it's a crapshoot from there, and the best pitcher in the world probably doesn't move our chances enough to justify the wins down the road. Statistically, make the playoffs every year with this high floor approach, play as many hands as you can. But also, I'm impatient and I like rooting for awesome players and winning now is cooler than winning down the road (and we should find/pay for/produce good replacement players later anyways). Go do something stupid.
