The Miami Heat blew out the Brooklyn Nets 103-73 [RECAP | BOX] at the American Airlines Arena on Wednesday night in the first meeting between the two teams this season. The Heat won all four quarters and quickly turned a solid 9-point halftime lead into a total laugh riot in the third quarter. The Big 3 looked on from the sideline, resting, for most of the fourth quarter. • LeBron James has said that, when planning to attack off the dribble, he concentrates first and foremost on reading the second line of the defense because he is confident he can beat his individual defender off the dribble. Against the Nets, “reading the second line of defense” could also be written as “looking at a wide open key.” The Heat’s much-ballyhooed position-less revolution was an absolute nightmare for the Nets, especially because Brooklyn’s most versatile player, forward Gerald Wallace, was sitting out due to injury. The list of resulting match-up problems for Brooklyn were just endless. The Nets’ traditional big men — center Brook Lopez and power forward Kris Humphries — were forced to follow Chris Bosh and Shane Battier all the way out to the three-point line. Nets guard Keith Bogans, inserted into the starting lineup in place of Wallace, was forced to check either James or Dwyane Wade. Those individual pieces were all problems but the Heat’s genius this season is in its “whole is greater than the sum of its parts” unselfish dynamic on offense, which sees spectacularly quick ball rotations and timely isolation plays to pick on weak defenders which seems to produce an endless stream of wide open shots and easy looks.
