What happened next will go down in football history as one of the sport's most fantastic finishes, a long-awaited answer to the original Hail Mary, with Roger Staubach's rainbow to Drew Pearson dooming the Vikings to a playoff defeat to the Dallas Cowboys 42 years ago. It took a gorgeous touch pass from Keenum, delivered over the outstretched arms of defensive tackle Sheldon Rankins; it took a tremendous catch by wideout Stefon Diggs along the right sideline, and the guts he showed in keeping the play alive, rather than stepping out of bounds; and, as almost always happens in such circumstances, it took a healthy combination of weirdness and luck.
