Josh Hamilton‘s new contract covers age 32-36. So I set out to find players from the live-ball era who were comparable to Hamilton from age 26-31, and see how they had performed at age 32-36.
Before proceeding, there’s one point that I failed to state clearly in the Greinke post: I am not analyzing the financial side of Hamilton’s contract. It’s too soon to gauge the impact of the recent revenue surge on the average cost per WAR on the free market, and there are too many other value factors specific to the situation. I’m just looking at on-field performance.
