If something is going to happen, actual rules and times need to be established. Clearly different people have different ideas about how this should go down but until rules and times are done, nothing is going to happen.
I will say, I would prefer short time windows to make your pick. If there are only 12 teams, a half hour to 45 minute window to make picks means the commissioner needs to be available 6-8 hours per day to do this right. There is no way I am making myself available 6-8 hours per day to commish this game. 2-3 hours, fine, but not 6.
