When team’s construct rosters they have a baseline of expectations from each of the players they choose to be on the roster. How they arrive at those expectations varies of course from organization to organization. However they all use some form of projections to set their baseline. Some teams may use sophisticated statistical models to forecast performance and rely heavily on them when constructing rosters. Others may use more basic forms of projection, and rely less on statistical models and more on scouting and coaching input. Regardless of where an organization may fall on that spectrum however, they are all projecting something out of their players.
