C Wilson Ramos: He stayed healthy throughout the season. Privately, though, some people in the organization worried about Ramos' game-calling skills. Ramos also had problems catching throws from the outfield. To make matters worse, he had his worst season as a hitter. This is a key year for Ramos because he is eligible for free agency after the '16 season.
3B Anthony Rendon: He was the club's Most Valuable Player in 2014. In '15, Rendon was arguably the most fragile player. He played in only 80 games because of a knee sprain and quad sprain.
