That's not how defensive rating works you idiot. Defensive rating is based on the lineups you're in - not your individual defense (unless you're a defensive anchor, then with the appropriate context it can be used). DWade comes off the bench, therefore he faces WORSE offensive lineups. If JR continued to come off the bench, and DWade was the starter, JR would have the better defensive rating.
Do you not see almost all of the bench players have the best DRTGs, whereas the starters have the worst?
Jeff Green has a better defensive rating than LeBron - does that mean Green is a better defender than LeBron?
Channing Frye has a better defensive rating than LeBron - does that mean Frye is a better defender than LeBron?
Kyle Korver has a better defensive rating than LeBron - does that mean Korver is a better defender than LeBron?
Jose Calderon has a better defensive rating than LeBron - does that mean Calderon is a better defender than LeBron?
First of all, the league-wide ORTG was higher last season, therefore by standard the Cavs had a BETTER defensive rating last season.
Second of all:
League /// Stats /// Cleaning the Glass (sans garbage time/possessions at the end of quarters) - last season in full, the Cavs had a 110.2 DRTG
League /// Stats /// Cleaning the Glass (sans garbage time/possessions at the end of quarters) - this season, the Cavs have a 110.5 DRTG
Furthermore, compared to this time last season:
They had 104.7 DRTG
this time last season - ranked 17th in the league -
Teams Advanced
They have a 108 DRTG this season - ranked 25th in the league -
Teams Advanced
Not only were you wrong trying to up that quote (why would you quote it in the first place, if you were going to post DRTGs that were identical?), not only were you wrong quoting DRTGs without the proper context, but you were wrong also because this time last season they had a better defensive rating too.
