First off, these are two outstanding defensive teams. Cleveland gave up the fourth-fewest points per game in the NBA while the Hawks ranked first in defensive field goal percentage and was the top-ranked defensive team since the All-Star break.

The Hawks held Boston to an average of 89 points per game in regulation during their last three games of their first-round series. The Celtics are a higher-scoring team than the Cavaliers. The under has now cashed in seven of Atlanta's past eight games.

Atlanta should be super fired-up to set a tough defensive tone having been swept by the Cavaliers in the playoffs last season. The Hawks are improved defensively this season, know the Cavaliers and LeBron James much better and have their confidence up after defeating the Celtics by winning Game 6 in Boston, a very difficult venue.

Then there is the rust factor - and it should prove huge. Atlanta last played on Thursday while Cleveland will be in action for the first time in eight days. The under has cashed five of the past six times when the Cavaliers haven't played in three or more days.
