Aside from the big 3 the unsigned guys are:
Stroman - maybe
Kershaw - no
Clevinger - maybe
Lorenzen - no
Woodruff - Paxton type deal?
Urias - jail time, pass
Manaea - no
Greinke - would be fun to watch, but no
Paxton - no
Giolito - sure
German - no
Boyd - no
Hill - retire please
Junis - relief profile, no
Wood - no
Ryu - medicals? maybe
Montas - bounce back candidate with upside, sure
Imanaga - midrotation guy, price tag?
Bauer - PR hit?
Carrasco - no
YRodriguez - relief profile, no
I guess it depends on which of the bargain basement guys Crag likes? Would he take Giolito and Montas thinking that he can put life back into them? Both had TOTR upside in recent years.
