Yes, once the league is full you may realign the divisions anyway you see fit. However, we must remind you that being the founder of a theme league places responsibility on your shoulders. Please do not make the experience a negative one for the other owners in your league. They are counting on you to run the league fairly and maturely. To realign the divisions, simply click on the "Realign" option that appears in the theme league guidelines box on the League Overview page when the league is full. This option will only be available until league play begins. Also note that if a schedule has been generated for your league, realigning will cause the schedule to be wiped out and a new one will need to be generated. This may delay the start of your league, so avoid realigning more than once if possible.
