I suppose this is as good a place as any for this question. Do the Brewers have to add Cain to the 40-man roster this offseason? I think the rules changed to 4/5 years in the last cba, but I am not sure how his draft/signing age is calculated for that purpose. On the same note, does anyone have a quick list of critical prospects that must be added to the 40-man this winter?
