Here's a napkin math hypothetical. If Kelly Johnson hits near his career mark, he's worth about 0 runs above average offensively. If Florimon hits like he did last year, he'd be worth about -25 runs in a full season. Assuming that Dozier pairs up full-time with either player, the question becomes, what is the total defensive difference between SS Florimon / 2B Dozier and SS Dozier / 2B Johnson? I'd put Johnson as a -5 at 2nd, Florimon as a +5 at short (not much to work off of), Dozier a 0 at SS and +5 at 2nd. That would give a 15 run benefit to the Florimon/Dozier combo defensively, but a -10 run difference overall. Hypothetically.
