Throughout the regular season the top defensive rebounding percentage was 80.7% and the worst was 75.6%
Here are the Jazz's defensive rebounding percentage numbers in the Houston series
Game 1: 79.5%
Game 2: 79.6%
Game 3: 92.7%
Game 4: 80.4%
So yeah, Rudy's rebounding is really a non-issue in this series. Houston's regular season offensive rebound rate was 21.3%, so Utah has held Houston below it's average in every single game thus far. Also consider we have no Rubio in this series, who is a top 10 rebounding PG in the NBA and someone who secures a lot of long misses of the team and averaged 7.3 per game in the OKC series despite only playing 7 minutes due to injury in the last game.
