People with anti-Duncan agendas like to point out the Spurs success this year as evidence that Duncan was overrated. However, Aldridge was brought in as Duncan's replacement, not Kawhi. If the system was so great for a big like Duncan, Aldridge who has been a multi-year all-star before Pop, would be elevated to great like Duncan. Pop runs a great system that props up role players, but arguable holds back star players while those role players get expanded roles. To truly shine in Pop's system, you have to be truly great. Duncan was truly great, so he actually shined. Kawhi is truly great, so he shines. Aldridge was just a star but not a great superstar, so he is not shining. Similarly, Richard Jefferson was a near all-star when he joined the Spurs, but had a massive drop despite still being in his 20s when he joined. Jefferson was nearly as productive at age 33 on a different team as he was at 29 fresh off a 20ppg season when he joined the Spurs.
