Tim Duncan did fine last year He went out on a 67 win team. Played very efficiently. He looked bad against the Thunder, but they made the warriors bigs look just as bad. i don't think it was so much Duncan's decline that made him look so bad, so much as how good Ibaka, Kanter, and Adams are. Three big, athletic dudes, you're trying to play against at all times. That's rough.
Drtg is a fine stat for a team, but it is fairly useless for a player. Notice the top 4 players listed at nba.com are Spurs. Also notice 8 out of the top 12 are Spurs. Also notice, LaMarcus Aldridge is rated the #1 PF, if you don't count other Spurs...ahead of Draymond Green. Don't use Tim Duncan's Drtg this year as a way to say anything. It's not a good individual stat. It is driven by the entire team's Drtg. It's a team stat. It's just, how many pts per possession were scored, while you were on the floor. Oh, and also notice Jeremy Lamb is rated #7 in the league...the #1 rated SG in the league. http://stats.nba.com/league/player/...G*60&Season=2015-16&SeasonType=Regular Season

He clearly wasn't the same player he was, and it can't feel good to be made to look bad by Ibaka, Kanter, & Adams when you were one of the greatest to ever play the game.
