Denver plays D by overplaying the ball and going for steals as a team, Martin and Anderson going hard for blocked shots. It's not a man-to-man grind based on D principles like Houston is - more like the physical play and dare the refs to call it of Utah. Denver isn't close to Houston's or Utah's discipline, fouls without hesitation and is just aggressive, overly at times.
Look at what Dallas scored on Denver in the playoffs - 95, 105, 105, 119, 110. Yesterday, LA blew out Houston but only scored 89. Points are going to come very easy in this series.
Look at what Dallas, who was 26th in the NBA at FTA at 22.6 per game, attempted from the FT line.
Game 1 - 13
Game 2 - 30
Game 3 - 49
Game 4 - 43
Game 5 - 29
32.8 per. This on a team of jumpshooters with no post threat. Denver's philosophy of not giving up easy shots and taking hard fouls is not the same as Houston's of swarming with everyone playing solid D without fouling.
Now, compare that to what LA shot against Houston - 19, 26, 33, 18, 36, 20, 18. Only 24.2 to a team that shot 25.5 in the season. Not a sharp decrease when averaged out but 5 games were well under average.
LA (especially Pau) goes into a tank when they perceived they are getting fouled but not going to the line - they will get plenty of attempts against Denver.
