Boston creamed: Cavs back home after demolishing Celtics

LeBron James wrapped up his postgame news conference, popped a toothpick in his mouth and pushed back from the podium as if he had just completed a satisfying meal.

He and the Cavaliers feasted on the Celtics.

Breaking records and Boston hearts, the defending NBA champions continued an unblemished romp through these playoffs — and on course to clash again with Golden State in the Finals — on Friday night with a 130-86 win that was so thoroughly dominating that James sat out the final quarter.

With Cleveland leading by 38 in the third quarter, Cavs forward J.R. Smith mocked some Boston fans by pretending to sweep a broom across their famous parquet floor.
