Yes, I agree that this is an incredibly under-achieving group. It's always bothered me how almost the ENTIRE staff can fail, instead of just a couple pitchers. This has to do with desire and focus.
Also, baseball players constantly report that they enjoy "having a routine", and "knowing my position" in the staff or lineup. With the Twins this year, the manager constantly changes the lineup order and bullpen order. Why was Rogers removed from closing at first? dunno. That has not helped him.
The constant shuffling of everything cannot be blamed on injuries. The players don't know their set position or have a routine, and it's June.
