I am not sure I want to know how you know.
Just sort of sampling league numbers - I could have likely narrowed it down further but against a moving target and considering my draft is going to suck anyhow, it wasn't really worth that level of precision. Still, just go to the league's home page (e.g., http://www.buzzerbeater.com/league/11972/overview.aspx ) and then just change league numbers, then check the lowest teams to see if there are players with 0 DMI and no draft history (though sometimes you need to check last season's draft history just in case). These are all mostly bot teams so filtering by age and looking for 0 DMI isn't enough, unfortunately.
