I just don't think it wise to rely on two rookies, one with zero MLB experience, one with 2 very good MLB starts (and 1 not-so-good), and a guy that isn't really throwing yet. I think the depth is somewhat smoke-and-mirrors. Anderson is pitching worse than last year, Davies has been hurt/ineffective, and we're lucky if we're getting QS out of the likes of Woodruff/Peralta/Suter/insert name here. Chacin and the re-emergence of Guerra have been bright spots in an otherwise fairly dismal rotation so far this year. They're doing enough to win, which has largely been a product of the bullpen eating 3-4 innings every single night, which has worked well so far, but that HAS to start catching up to them. I don't think we have the luxury to let a guy like Burnes adjust to the majors in the middle of a playoff race. I should clarify -- I think between Nelson, Peralta, and Burnes, our options are likely in-house long-term -- not necessarily this season. I'm ok with selling off decent prospects that are potentially part of the roster crunch anyway, for upgrades anywhere, not necessarily starters. I don't think it would be wise to sell off major assets because of not wanting to count on Peralta, Nelson, and Burnes for postseason 2018. We're not as good as the Cubs are yet, and someone like Happ doesn't change that. This could be a wild card team, but I'd rather roll with who we got and see what happens rather than invest significantly in a 1 game playoff. If you want to sell off guys out of roster crunch guys to give us a little better shot this year, sure. But this team should still be looking at the big picture. Bingo.
