DBacks have a completely traditional (or, as they call it, 'real') approach to baseball. They liked Castillo so much cause his fastballs are fast. Makes me kinda wish we had a Junior Lake in the org, a raw but athletic AAA guy is exactly what they'd want for Miller at this point. As it is I see them asking for one of Eloy, Cease, EJM, or De La Cruz (in suspected order of preference). One might be able to sell them on Underwood and a rookie-league type tho, since Underwood's pitches are generally well-respected. I may be ignoring a Theo tax - was it Towers or Stewart who was afraid to deal with Theo? Candelerio, one of Tseng/Underwood/Johnson, one of Sands/Steele/Paulino/Clifton/Twomey/Hudson/Kellogg.. basically, any non Cease/De La Cruz/Moreno A/A+ pitcher. More than he's worth, but I'd be ok with letting them save face in hopes that Bosio can fix him.
