LeBron James delivered the go-ahead jumper with 30 seconds left to help lift the Los Angeles Lakers to a 114-112 victory over the Boston Celtics Sunday as the two decorated franchises renewed their historic rivalry. "I just gave a little dream shake to the baseline and was able to open up the middle and get my fadeaway," James said. The NBA powerhouses went down to the wire in a back-and-forth thriller in front of a crowd of almost 19,000 at the Staples Center arena.
