A collection of data corresponding to a player is assembled at a server from a data provider. A base value of the player based on at least the primary data is added as an attribute to an internal object stored at the server. A modifier is mapped to a second attribute of the internal object. The modifier is based on at least a portion of the secondary data and the tertiary data. A projected value is generated from the base value by applying a modifier and a rule converting the modified second attribute to a projected value. Internal objects are generated according to constraints including having a sum of limiting factors of the internal objects that does not exceed a maximum factor and a sum of projected values a maximum, subject to the first constraint. The server transmits application data including a list representing the internal objects.
