I like the idea of getting Salty and all, but wouldn't 3B be more of a need given that Towles is at AA, and could (not saying it is smart to do this) be in the ML as early as next year?
I am not writing off the team this year, but I think it very prudent to keep beyond this year in mind, especially when trading away your #2 this year.
And beyond this year, you have the potential of Albers and Patton and Backe to fill rotation holes (I will let you pick how well each might do that), and you have Towles and some A-ball guys at Catcher... and you have some potential bullpen types as well, but you lack OF, take your pick of RF or CF depending on where you want to "stick" Pence (I do like Flores potential), and you lack 3B... Heck you even have potential need at 2B as most are not sold on Burke.... I am going to stick with Everett at SS unless some fool wants to give me something better.
