Many players come up to the majors and struggle. That doesn't mean they were rushed. Arcia has shown he can hit AA/AAA pitching. He wasn't rushed. He is struggling to learn how to hit major league pitching. Hicks, on the other hand, has never dominated a level. The need for a CF rushed him and somewhere on the path he lost any power he had in his swing. I am not sure he can get it back and I am not sure he has the make up to deal with struggle. I hope Hunter can help with the make up and preparation. Hunter knows what it was to struggle when he arrived and how to work through it. If any player shows dominance at a level over a half season, moving them up is not rushing. If any of Sano, Rosario or Buxton dominate into June this year, it is time to make space and let them begin the struggle with major league pitching.
