With free agency officially underway, it seems like an appropriate time to see how the Yankees fared financially in 2015. As most baseball fans know, the gap between how much players make and how much they are actually worth can vary greatly. Older, declining players tend to rake in huge sums of money as their production falls off thanks to long-term contracts signed in their prime. Younger players who produce at a high level make peanuts in comparison, as baseball's current collective bargaining rules keep players' salaries under team control over the first six years of their careers.
