Shields is no longer a great pitcher but would be an upgrade over much of what the Twins can offer next year. I don't buy the Twins have a rotation glut, either on the majors or the minors. Outside of Berrios I wouldn't count on anyone in the minors making a quality start next year. Padres might be willing to deal him because presumably they are looking to reset/reload what they have and Shields, while an acceptable middle of the rotation guy, is overpaid, and there is significant risk over the next 3 years. Twins can take that on if they are able to dump Nolasco. They question is how good is Shields. His k rate is up, though NL probably inflates that. His bb rate is way up and his hr rate is huge. Question is if the bb rate is a blip and if hr rate is a fluke. Target Field can supress lh power, so that would help him, and the Twins of defense should be significantly better than the Padres this year, which would also be a benefit. A move I would make if the Padres are interested in moving him and if they have interest in players like Plouffe/Santana/Polanco/Stewart in addition to taking on Nolasco. And I would certainly expand it if they want to include a catcher.
