I don't think we can discount Bundy moving out of OPACY and the AL East for this as you said. The one item that is most missing during anyone's assessment of Bundy is that Mickey Callaway is the Angels pitching coach. A great pitching coach is still needed to relate to the player and make sure they are getting everything out of the data presented to them, and Callaway is one of the best.
Could be a variety of factors playing into that. ERA is a good stat, probably the best of all of what we call traditional stats, but it is still limited. Due to some defensive improvements this year, it might be best to look at FIP to see how our pitchers performed. They may also have their own expectations for how each pitcher should see improvement, and maybe enough pitchers didn't see improvement to justify keeping Brocail.
The other point being brought up about the minor leagues being condensed and more coaches available is an interesting one. Seeing Dylan Bundy succeed with Mickey Callaway also highlights the need for a great instructor who can translate things from analytics and communicate one-on-one with the player.
This is a crucial hire to get right.
I'd been thinking the last hour Dylan Cease is going to have to have his Ubaldo moment (except with "no one" rather than Zach Britton behind him), but I only now saw they burned him for an inning down 5-0 yesterday.
I guess that leaves Jace Fry as the last non-Colome reliever.
Ball now back in the White Sox lineup's court to escalate the drama further.
