Huge fantasy Baseball KEEPER trade HUGE?

Heck no you don't do it? Where do you come out ahead? You don't need Butler. With Cabrera and Aramis Ramirez, you are solid. Your weakest IF is Alexie Ramirez and your trade doesn't replace him. Don't make the deal. If Sheets has a come-back year, you will be kicking yourself. Same with Webb. Bad deal for you, good deal for him.
