Jesus fucking Christ Kopech has over 140 innings of experience in Triple A and was the hottest pitcher in MILB over the past 2 months and people still want to keep him down.. SMDH...
There is a lot that goes into play about these decisions than just that extra year of control, which may not matter as much at the end as the people here are fussing about. If you look at Kopech's overall body of work, he's proven he's ready the past month or so, and he most likely have "checked the checkboxes" with the organization. How do you tell the kid at the point that he's still not getting the call if he has done what the org has asked him to? On the flip side if you want to build some good will with Kopech (and Eloy) to leverage during contract extension discussion, these are the moves you make. If you handle their development solely based on financial reasons, that makes it much, much harder for the Sox as the negotiation table. Also, remember the backlash Cubs have gotten from the MLBPA after keeping Bryant down in 2015?
More importantly, if we want to help Kopech become better as quickly as possible, this is the move you got to make. He will learn from this next month and a half and hopefully makes adjustments in the off season and be more ready next year. The quicker Kopech becomes good, the less time we waste on Rodon, Moncada, Lopez, Gio, and TA's contract. I also think an important point being ignored here is if Kopech and Eloy come up and show they're the real deal, it will be a lot easier to sell to the upcoming FA class that we could be a winning team in 2019 or 2020.
