You don't fire the front office. Those guys can't be blamed for players under-performing. But we do need new eyes and voices around these guys.
You fire the following: both hitting coaches...I've never seen a team with 2 hitting coaches...too many voices to listen to, plus new eyes can see new issues. Also, it can't be just a coincidence that this many of our players are currently having career worst seasons.
I still have no idea how John Mirabelli still has a job with the Indians. He was our Scouting Director for 2000-07 (don't think we need to bring up how poor some of those drafts were), and is now in the position of "Senior Director, Scouting Operations". We need stronger voices in the front office when it comes to scouting, both pro and amateur players. You also let go of whoever is in charge of Pro Scouting...these are the guys Shapiro and Antonetti base their free agent preferences off of, and the guys who can talk them out of certain players. New voices can be good to hear.
After that, I don't think there is much in the way of the Indians being right back in the thick of things next year. The farm system is being built back up pretty well right now, we are graduating players to the big league club who flash, and another crop is currently knocking on the door. I do think you look to trade Murphy and Raburn for sure, maybe Moss, maybe Santana, maybe Lonnie, and see if anyone gives us a Bartolo Colon-esque return on one of our starters not named Corey Kluber.
Baseball is such a fickle sport. This team could be put together exactly the same as it is currently next year, and the results would be incredibly different, for better or for worse. The Twins are a shinning example of that this year.
