The WS believe they can compete next year in a weak AL Central, otherwise they'd be moving Eloy and Lois Robert Jr.
If they are shipping out Cease, its not unreasonable to expect they would want to get a starting pitcher who is cheaper and has more years of control in return. Also, they have perhaps the worse defense in the AL and just shipped out one of their infielders (Burger). Urias replaces Burger and dramatically improves their D.
