(CNN) -- By now, you've likely seen the shocking video -- professional football player Ray Rice punching his future wife out cold in an Atlantic City casino elevator and dragging her limp body out. There's been so much to this saga, much of it developing very quickly every day this week. The latest is that the NFL has hired former FBI director Robert Mueller to lead an investigation into how the league handled the case involving the ex-Baltimore Ravens' running back. We have to say former because Rice was fired this week. In this important story involving arguably America's most treasured sport, who said what when? Who knew what when? And where is this all going?
