In my opinion, it'd have to be something really, really bad, for DM to do it because firing Ned would basically mean conceding that the season is over and they have nothing to play for. 10 games under at the All-Star Break would be my guess, unless he publicly disgraces the franchise by pulling an Ozzie Guillen or something. Of course, an Ozzie situation would never happen in Milwaukee because the sports media is too spineless to actually ask a tough question every once and while, but that's a different topic.
