Does the "-1" next to Pomeranz' name mean I need to promote him? He's not getting a card in 2014 (listed as "Computer only" player). Do I still need to promote him?
No, Pomeranz does not have to be promoted, prospects have to be promoted if they are carded for more than one season.
I put a 1 or 2 next to some prospect's names based on my guess of how many carded season's they will have. It's not "official', just a guide/reminder for everyone. If they have a 2 then they will have to be promoted (unless I guessed wrong about them receiving a card).
