From these four inputs, we can first project Greinke's performance in WAR, then figure out its "value" in dollar by working out what the cost of each WAR will be for future seasons, and multiplying that by Zack's expected contribution to the team.to cost each year. Sum his value for each season, and we can see how the contract cost compares to his expected value. Below, you'll find a spreadsheet where you can try out various combinations of the above variables in the top four rows, and the rest of the table will then update to show you performance and value over the length of the contract, and how total cost compares to the total value.
Will the Zack Greinke contract be good or bad for the Arizona Diamondbacks?
