There's not much to write, tbh. Duncan is an absolutely great talent to build teams around, but the fact that the Spurs managed such steady and prolific success cannot be attributed to luck alone, or mainly, especially when talking about a position as crucial to a team as Head Coach. Pop has been at the helm of some of the most innovative and successful offenses & teams through the years, managed to coach a mul ude of teams and personalities to championships, and also managed to make the most of scrubs to maintain a two-decade long span of unending success. The fact that comparable talents to Timmy (Hakeem, for example, or anyone you'd like except for MJ and Russell) don't have as many rings as him speaks to his talent, to his teammates, and also to his coach and winning situations he was put in. And that's not to even mention Pop's accolades or career milestones, which haven't been a fluke.
Thinking back, I could've just replied " '14" and be done with it, it was that easy. But I felt like expanding. Pop is ridiculously over-hated here - posters just want to be contrarian to the public opinion for the sake of it. But Pop, even if he's 70 now and should've retired 2 years ago, is still a Top 3 all-time coach, tbh.
