Woops, think I mispoke earlier. But here's the projected improvement we can count on compared to last year.
In 362 PA last year, Barney was worth -0.6 WAR.
In 459 PA last year, Goins was worth -0.3 WAR.
In 324 PA, Steamer projects 1 WAR for Diaz.
In 339 PA, Steamer projects 0.9 WAR for Solarte.
So just kind of eyeballing it, we are looking at a 3 WAR improvement or so from our backup middle infielders.
