Kris Bryant spent half of a season at AAA, before getting sent back briefly in 2015.
Eloy Jimenez's time in AAA will be less than a half a season when he goes back next year.
Vlad Jr spent 30 games at AAA.
Peter Alonso has spent about as much time at AAA as Kris Bryant.
All of these guys are causing outrages for spending about half a season at AAA. Kopech has already spent about a full year at AAA. If he hadn't been recalled, and had been sent back to AAA to game service time, we will be trying to say that the top pitching prospect in baseball needed parts of three different seasons at AAA, despite the numbers he was putting up.
It is becoming harder to justify the first four scenarios, and those guys are talking about filing grievances. I have NO idea how you could justify leaving Kopech at AAA AND THEN sending him back to AAA again next year. I get wanting the control, but let's be realistic here and recognize that these scenarios are NOT the same.
