Valbuena's skill set is precisely the type that doesn't result in inflated paychecks. So I'm not too worried about his escalating salary. I'm not against a Castillo signing. But his Cuban league numbers aren't all that impressive and the scouting reports are contradictory. All I'm saying is that I want to know more about what type of player he is before I get upset that the Cubs are or aren't willing to offer a certain amount. I am moderately interested in seeing how Renteria would try to cycle Castillo, Alcantara, Soler, Bryant, Baez, and Valbuena around in a lineup. But unfortunately there's not an easy platoon option that I see.
