I would think Dallas is a great fit for Taylor. That's a team built to win right now, with an owner that has a true sense of urgency. Its coach wants to run the ball ... Taylor would take a ton of pressure off Prescott ... there's a strong O-Line.
Right now, I put the Cowboys behind the Eagles and Evil-Niners in the weak NFC. Add Jonathan Taylor for a couple of draft choices (not a #1 ... maybe a #2 and #4), and I would put Dallas right there with Philadelphia and Satan's Team.
Again, when I throw-out these ideas, I can not stress enough ... I don't know what the Hell I am talking about.
