They are two different kinds of dollars amount here: a. B-P's VORP, fangraphs "value" and their derivatives, which calculate someones' performance, add a position-based replacement "value" and give out a dollar amount. And the idea here is grading on the curve. Cs, SSs, etc are rarely among the top bats out there. b. Market-driven contract actual dollar amounts. a and b are not related, other than they are represented with the same measurement unit. Think 20 pounds (sterling) and 20 pounds (of steel). (and, yes, the British coin used to represent the value of weight of one pound of sterling silver, thus the name) You are talking about a., while b. is the reality. Contracts are market-driven. And one cannot calculate the market, because it runs on supply and demand and (in baseball) on crazies who want to outspend each other. Last year, the Mariners spent $240M for Cano's ages 32-41. The Yankees spent $153M for Elsbury's ages 31-38, the Rangers $130M for Choo's ages 32-39. That establishes the market (and I expect that this season, it will get about 10-20% higher. The Twins spent $184M for Mauer's ages 28-35. Which of those 4 contracts will be a better value? Time will tell, but methinks Mauer's. Thus, the Twins got Mauer bellow market.
