For years, I have criticized general manager Brian Cashman, often berating him repeatedly in many of my articles here at the BBB. This season, I have come to the realization that Cashman has actually done quite an amazing job over these past few years. Don't get me wrong, Cashman has had his share of mistakes. We need look no further than his decision to give up Martin Prado for Nathan Eovaldi, give Chase Headley a four-year contract, or hand Ellsbury $153 million over seven years. The past three seasons and offseasons, on the other hand, have been a different story. The vast majority of Cashman's moves have been so brilliant that I've decided to reverse course, and praise a man I formerly had nothing but scorn for. Below, I identify and elaborate on Cashman's five best moves these last three years, and explain why these transactions have been essential to the Yankees 2017 success.
