I just do not see the Bulls taking a 3 games to 1 lead in this series especially with the injury to Rondo which opens huge doors for Isaiah Thomas.
Look for the Celtics to bring their A game to the court as they will exploit the Bulls weaknesses forcing many turnovers along with playing excellent in transition and perimeter defense against Dwyane Wade and Jimmy Butler which could very well produce a game that the winner barely scores 100 points. Also look for Al Horford to put up some big numbers and stymie the Bulls defense down on the blocks.

The Celtics relied on a balanced scoring attack to build their lead in that critical game three matchup. On the other hand, the Bulls struggled with pace in their first game playing without injured point guard Rajon Rondo. Unfortunately, the Bulls won't have a lot of time to make the adjustments they will need to get to within a game of closing out the Celtics. The Celtics shot a series-high 47.7% from the field which included 17 three-pointers, and played much stronger defense than in game two.

Boston has got their swagger back on the road, away from the heavy hearts at home. Chicago can not win with Butler trying to score every trip down the floor. Boston played great team basketball and had 34 assists to Chicago's 14 assists.
The Celtics looked great in both ends of the court in game three and they now have momentum and confidence back on their side.
The Celtics team featured more scoring punch, and overall they are the better team here and even up the series with a win on Sunday.
