The Yankees had no business winning 85 games last year, they were outscored by opponents and had a second order win-loss record of 71-91. In order to be competitive, they have to improve by almost 20 wins. So far, they’ve lost Cano (6.0 WAR), Pettitte (3.2 WAR), Rivera (1.5 WAR), Hughes (1.4 WAR) and Granderson (1.4 WAR) to free agency and retirement and added Ellsbury (5.8 WAR), Brian McCann (2.7 WAR) and Carlos Beltran (2 WAR) for a net gain of -3 WAR. The last time Jeter was healthy, he was worth 3 WAR, the last time Teixeira played 100 games he was worth 2.7 WAR. Now we’ve arrived at a net WAR of +2.7. Even if you subtract every negative contributor to their WAR last year (assuming they won’t be dragging the team down next year), that’s another 6.8 WAR. Nowhere close to 20 wins. It doesn't even add up to 80 wins.
