Instead of signing Drew, Epstein could have chosen Alfonso Soriano ($136 million, eight years), Carlos Lee ($100 million, six years), Gary Matthews Jr. ($50 million, five years), or Juan Pierre ($44 million, five years).According to the value estimations on fangraphs.com, in the three years since those deals were signed, Soriano has earned $33.4 million (8.0 wins above replacement player), while being paid $41 million. Lee has earned $40 million (9.2 WAR), while being paid $43 million. Matthews has earned -$5.2 million (-1.1 WAR), while being paid $26.2 million. Pierre has earned $15.4 million (3.6 WAR), while being paid $25.5 million.And Drew? Even with a rough 2007 in which he “earned’’ just $5.6 million (1.4 WAR), Drew has earned $45.4 million (10.3 WAR) in Boston, while being paid $42 million. So, in the warped world of baseball finances, the argument could be made that Drew is underpaid. Or, perhaps, that he is compensated equally to his value.
