If it's 6-8 weeks then you keep Albies and Swanson down for 6-8 weeks. Having them come up and participate in a year where you aren't going to win anyway and giving up that back end year just isn't good business. Now, 12 weeks changes things because then you have to hold them down for 1/2 the season. To me the 2017 season should be most of the near ready young talent at the ML level playing together and developing as a unit throughout the last half of the 2017 season. It also allows you to spot or reinforce previous thoughts regarding holes in the line-up, rotation and pen that need to be addressed before 2018, through the very fertile FA class.
