Pour Samuels, c'est utile de mettre son defensive rating avec de rating différentiel, qui en l'occurrence est un des plus mauvais de l'équipe, et aussi il faut savoir que c'est une stat où les intérieurs sont naturellement avantagés.
Au passage, d'ailleurs, le meilleur defensive rating du CSP est plus mauvais que le pire defensive rating de l'ASVEL (qui se trouve être... Kahudi).
Out of necessity (owing to a lack of defensive data in the basic boxscore), individual Defensive Ratings are heavily influenced by the team's defensive efficiency. They assume that all teammates are equally good (per minute) at forcing non-steal turnovers and non-block misses, as well as assuming that all teammates face the same number of total possessions per minute.
Perhaps as a byproduct, big men tend to have the best Defensive Ratings (although Oliver notes that history's best defensive teams were generally anchored by dominant defensive big men, suggesting that those types of players are the most important to a team's defensive success). A corollary to this is that excellent perimeter defenders who don't steal the ball a lot — for instance, Joe Dumars or Doug Christie — are underrated defensively by DRtg, and are prone to look only as good as their team's overall defense performs.
