Just thinking off the top of my head: Barry Sander's senior season is still astronomical. ...and (showing the bias) so was Jamario's fresh season. What about MMA? The Gracie family's old streak... I can't recall his name, but I know that it is a South American (Brazil, I think) that is the international basketball career leader in points scored, and it is not even close. The guy refused to play in the NBA Lance's streak in the Tour de France. What Roger Federer is doing is nothing short of remarkable. There have been a few instances where a college defense held the opposition to negative net rushing (it was done in the Sun Bowl Game not too long ago). I know that many of those I have listed blur the debate between single instances/games vs. streaks over long periods of time. But still, might not be a bad theme for a new thread.
