The Boston Celtics destroyed the Lakers by 39 points in a rout of historic proportions to win the NBA championship for 2008.
I've never seen a Lakers team get rolled this badly in such a decisive contest. And neither has anyone else. The Celtics' 39-point margin of victory was the greatest in a clinching game in the history of the NBA Finals.
As my friend's grade-school-age son noted, when he added up the differential in the closing seconds and noted the Lakers were down by 40: "Hopefully we'll learn from this for next season."
