just like last years game 5, the Lakers were trailing as high as 25 points somewhere in the game. They came to as close as 2 points in the ending of the game, and Robert Horry took a 3. He missed, and Spurs won by 2 points...
.... things like that happen quite a lot now... shouldn't be too much of a surprise if we see it along another playoff game, just as how the Kings caught up in the 4th quarter, tied it, but lost by a 1 point game in OT.
