Yes Gibson, May and Meyer are the main talking points when questions arise about slow promotions. Gibson and May have struggled upon their arrival, but that doesn't tell me the club was right to wait, it tells me the opposite. They were viewed as "ready" before their call up yet they still struggled implying being "ready" doesn't occur until they get acclimated to the MLB. Gibson should have been allowed to struggle in early 2013 with the hope he'd be useful at the end of the season and closer to his potential to start 2014. The same should have been done with May. This team has been historically awful, yet they seemed to keep the young arms down at least in part because they didn't want to chance making the MLB product worse. If that played any part in the decisions, and I'd bet it did, they were very short-sighted. I don't know why there is an idea that guys have to learn in the minors and education ends upon a call up.
