In case you haven't yet noticed, there are 10 positional programs that don't roll up to someone. There are 6 open program souvenirs in the Career Arcs (12 in Immortals). So a 1B, CF, LF x2 are available. So who split time in their career at center, left and first?

Ryan Hanigan - C - Carter? Chris Carter - 1B - Molitor? Lucas Duda - 1B Neil Walker - 2B - Utley? Darwin Barney - 2B - Utley? Alejandro De Aza - CF Daniel Nava - RF Matthew Joyce - RF Al Alburquerque - RP - Hoffman? Junior Guerra - CL - Hoffman?

For the Immortals, Each need another souvenir... So maybe they just reuse some of the already existing career ones? But just something that stood out to me while creating a worksheet to keep track of the missions.
