That not really true. Daniel Murphy was signed for 3/37.5. Elite middle relievers get less. Andrew Miller was signed for less. Elite international FAs sign for less. Vet middle of the rotation starters get close. Granted there are many FAs that don't make it, but you have to have trust in yourself to be able to spend that money wisely.
Middle releivers are the worst value $$$/WAR you can do on the open market. International FA are a total grab bag as we've seen recently. Sometimes you get the guy who the White Sox got. Sometimes you get Olivera. Vet MOR do get close but the Braves are spending money on that. They would be spending money on position guys. At 8 or so million per way if you are spending it on the FA market you are getting a 1-2 WAR player. No impact players. There are exceptions to everything though.
