Adding a #1 or #2 starter to this team would be adding nothing. You would get a net gain of nothing as the win expectancy of this team wouldn't increase any higher than what it is by getting a #1 or #2 starter. Basically adding another #1 or #2 puts the team at an 81 win team instead of an 80 win team. You are adding one win to a team that is barely a .500 club to a .500 club. Why would you trade assets only to get a +1 win? Wait what? So you're saying, hypothetically in the off-season, if the Mets were to make DeGrom available, or the Giants were to make Bumgarner available, like Sale became available last off-season, and we were to pull a blockbuster and acquired DeGrom or Bumgarner in trade, and either traded Garza or let him walk, DeGrom or Bumgarner over Garza in the rotation is worth 0-1 additional wins over the course of a full season? There's no way that's true.
