I really think it comes down to two things and I know it has already been said but... Where is our top of the line arm going to come from? are we going to be able to find that ourselves or will it require a trade? Can Medeiros become that guy and harness some control/more velocity? Will Hader beat the odds and make it as a starter...more importantly a really good one? My other concern is you need some stud guys on offense too. Who are those guys going to be? Is Arcia going to translate offensively at the top level or is he going to be closer to an Alcides Escobar player? What about Clark, Lara, Gatewood, and Harrison? Will some of those guys make an impact before 2020? Put it all together and aggressively you are looking at a .500 team in 2018, but if you ask me it will probably take another year or two after that to truly put a talented team on the field. I like the future of this team a lot, but to get over the hump we need a top of the line starter and some studs on offense.
