Taking a two year perspective

The main reason WAR exists is to balance offense and defense in a scientific way rather than just making broad statements that one is more important than the other.  But your point is correct.   Even a bad major league fielder makes almost all the routine plays, so the run impact of a good fielder vs. a bad one is not as big as the impact of a good hitter vs. a bad one.   There are only about 5-6 plays a game where the skill of the fielder really comes into play, but the skill of the batter matters in every at bat.   

Well said, to explain why offense is more impactful, in a quantitative way. A similar approach makes WAR also a fair measure to compare pitchers with hitters. And for the hitters, the variations of WAR give us the actual breakdown of the offensive and defensive portions of a player's total score... Which works out to, what, like a 4:1 difference typically?
