Even if you include all the smaller players for 2019, it only adds .6 WAR and probably close to $3-4 mil in salary so it doesn't help any. 4.7 WAR from FA players. That's awful. And I get some of these names can be argued but baseball reference listed them as being acquired as FA. Players released while still under control are counted as FA.
