NBA: Why was David Robinson's final season (2002-03) better than Tim Duncan's final season (2015-16)?
David Robinson started all 64 games for the Spurs in '02-'03, making him the starting C for them. However, he only averaged 8.5 points, 7.9 rebounds and 1.7 blocked shots per game in 26 minutes per game, so I think he should've finished his NBA career as a backup behind Malik Rose at C instead of having Rose back up both Tim Duncan and D-Rob simultaneously.
To be fair however, Tim Duncan's 2015-16 saw him average 8.6 points, 7.3 rebounds and 1.3 blocked shots per game in 60 of 61 games started. I think Duncan should've also played his whole final season as a backup PF/C behind David West and LaMarcus Aldridge simultaneously instead of shoving West into a backup role.
Both Spurs legends had their sole seasons of career-lows as former stars turned fringe players on their final swan songs.
But anyway, why do you consider David Robinson's 2002-03 season to be much better than Tim Duncan's 2015-16 season?
