No way. Think AJ Burnett. A return to familiar confines is all a to shelf player needs sometimes to return to form. Shields is a steal at 10mil/year. Bet on it. His XFip over the past month was top 20 worthy (3.25) on that horrible team even taking into account that one real bad start.
As a Yankee fan I love it. He will probably go 4 wins 9 lost before being dfa.
