Bryce Harper won the National League MVP award on Thursday despite a highly disappointing season for the Washington Nationals.
Harper's 2015 output will go down as one of the best in Major League history, perhaps one of the top 50 to 100 ever.
FanGraphs has a formula for converting a player's WAR into his monetary value on the open market. The site calculates how much teams spend per projected WAR and then applies that "market price" to each player's output at the end of a given season.
On average teams were willing to pay about $7.7 million for every additional WAR this season. That means Harper's 9.7 wins above replacement would have been worth $75.4 million on the open market.
That $75.4 million figure is the most that any player's season has been worth since 2002, the first season FanGraphs made the calculation. Harper is also valued high due to the growth of salaries. Barry Bonds's outrageously great 12.2 WAR was worth "just" $46 million in 2002.
