Why did we forget?

Why did we all forget about when Peyton Manning threw a 4th quarter TD in 2004 to beat the Texans 49 to 14? Why isn't that running up the score? Or when they scored with a minute to go in the game to beat the Titans by 31 in 2004, isn't that running up the score? What about all of the shelackings the Broncos put on teams in 98', why was that not running up the score? I remember elway threw a TD agaist the Seahawks with about 10 seconds left in the game to win 35 to 3. Not running up the score? HMMMMMM, seams a little fishy to me.
