You could have a manager with Einstein-level math skills and I don't think it would help that much with this collection of guys. That said, I was against bringing Snitker back.
I don't mind giving vets that benefit of the doubt, but Johnson has been so bad over his past few outings that they should simply put him on the DL for nausea symptoms (not his, ours when he pitches). What should be happening is that guys in Gwinnett who are on the 40-man (Morris, Hursh, Burgos) should be in the pen showing what they might have and whether they are worth retaining. Now that Winkler is up, he should get extended action as well. My guess is Motte, Brothers, and a couple of other bullpen guys will be dropped after the season, so I don't know why that isn't done post haste.
