I've set up a 12 team keeper league that starts this year. 14 keepers can be kept, and the max roster size is 20. Since owners do not HAVE to keep 14 players (I'm assuming this is the rule?) if an owner chooses to only keep 10 players, does that mean the draft will automatically change to a 10 round draft, since the owner needs 10 picks to fill their roster?

Also, say someone does keep the max of 14 players, but they traded for additional draft picks prior to the draft, and they have a total of 8 picks. Since the max roster size is 20, does the system automatically remove their last 2 picks in the draft so they have an even roster like everyone else?

I guess basically I'm asking if this balancing is done on it's own, or if not then can it be done manually at least?

Thanks!
