In regards to the question about keepers, you cannot "keep" them beforehand. When you set up the league you can go into commisioner tools and adjust keeper settings. Or the next season within the same league you can choose keepers.
Thanks, Drew. I missed your message yesterday. What I was interested in was whether there was a way in which the keepers can be inserted prior to the beginning of the draft by the commissioner three spots prior the round in which the player had been drafted in the previous year.
I also was interested in knowing whether a draft round traded to a team the previous year could be added in exchange for the removal of the previous owner's round's pick.
