At this point in the fourth quarter, a comeback was definitely a long shot and LeBron's complaining to refs was of course going to get this kind of reaction out of a raucous crowd.

LeBron had one of his quietest games of the playoffs finishing with just 15 points, 9 assists and 7 rebounds while shooting 5-of-16 from the field and 0-for-5 from downtown. It was the 3-ball that hurt the Cavs more than anything else perhaps as they went 4-for-26 as a team while Boston hit a solid 11-for-30.

The Cavs will need a completely different performance the rest of this series if they are going to come back and make it competitive. With LeBron on their side, the likelihood things get more competitive is definitely high, while the Celtics are happy to have sent a strong message in the first game of the series.
