I'd just as soon hold off on Shields now. If we ARE contending, we can add mid season, if necessary. If we're not, or if we are and address other needs at the deadline, we can get a guy next offseason. Some of them will be available for sure anyway. Only way I go after Shields is if he'd sign a 1-2 year deal(very,very doubtful in my opinion) or if the FO knows they can sign him AND it doesn't change the fact we'd still have room to grab another one next offseason too.(I'd be shocked if we had the capability to add Shields + Zimmermann/Price/whoever.)
