I cannot imagine any combination of Pearce, Thornburg, Travis, Lin, and Hernandez bringing back a reliever worth acquiring. Johnson is a tough call, as he is cheap, controllable, and left-handed. But you’d need a GM who values him a lot more than me. I think every team already has a Brian Johnson or two somewhere in their system already. Heck some of them might even be named Brian Johnson.
I guess if you’re taking back a salary dump like Mark Melancon or Jeff Samardzija, it might work. Maybe...
