All the top-end players get half of their FG value. As you know the #1 players each year are worth $60M ...
In terms of bases gained and lost, if you compare top-end players to normal players. GM's don't pay $50M per year to anybody because they don't want to wreck the salary structure. If you're using the "normal player bases" metric, the top end players are indeed worth their $/WAR; if you use the jimmied-gamed "industry salary structure" that is what is fishy.
....
Of course there has always been the org that, in the past, went ahead and smashed the industry salary structure for a Manny or ARod, and caught huge flak from the commish for doing so.
For whatever reason, the talking head sabermetricians CONTINUE to pummel orgs for every CC Sabathia type contract; I don't know why they continue to overlook that in the first halves of their contracts, most of these FA's are earning twice their salaries.
