The pitching staff underperformed its FIP and xFIP by nearly 1/3 of a run. Hitting their FIPs (normal luck on BABIP, stranding runners, HR/FB) would have resulted in about 45 fewer ER allowed.
The 80 unearned runs the defense allowed were by far the worst of the Gardy era. There were some exceptionally good seasons in there, as well, but a typical Gardy team allows a UER total between 50-60. Let's say that normal (not necessarily rangy, but pretty sure-handed) Twins defense would have subtracted 25 UER.
By combining the FIP with ordinary defense, the Twins could have shaved about 70 R off their total. That would probably include the 10 Teflon already suggested, though.
