You may change your Bench Player(s) three times in the first half of the season and three times in the second half of the season (up from just twice last season). HOWEVER … there must be twenty-one (21) days between bench player transactions.
This is going to be one of those seasons where they don't win many < 4 run outputs. Yes - it's like that most years, but I don't know if they have the wherewithal to withstand onslaughts of runs + good pitching.
