BOSTON — With a little help from his friends, though not that much, LeBron James dazzled once again in a playoff elimination game, sending the Cavaliers back to the N.B.A. finals on Sunday night and keeping himself in a Cleveland uniform for at least another two weeks.
In a game that looked bleak at the outset, with the Cavaliers playing without the injured Kevin Love, James powered an offense that started the game atrociously and then did just enough to break the upstart hearts of the young Boston Celtics, 87-79, in Game 7 of the Eastern Conference finals.
