I think Rasmus + Boni (or Izzy) for Murphy + Rafael Montero would be a better fit. Tapia may have better upside, but Montero should be able to step into the rotation right now if needed, and certainly should be ready next year as the depth we've been missing. He probably has #3 or #4 upside, but I think he's almost guaranteed to reach it. Fastball in the low 90's, but incredible control with 1.4 walks / 9 the last 2 years and 1.5 over his minor league career. Good k rate too, although it's hard to tell if that will translate as well to the majors.
