A baseball geek might say he was worth it, using WAR.
A win-above-replacement is worth $8 mil, so Greinke’s WAR of 4 or so would be worth his $30+ million annual salary.
So a 4 WAR would be worth $32 million.
How would a WAR of 4 or so make Greinke worth it for the Giants. Would that be four years of playoff baseball and sellout seasons?
