The San Antonio Spurs of the 2000's and early 2010's with Tim Duncan, Manu Ginobili, Trey Parker, Bruce Bowen won most of their NBA Titles arguably to stiff, lock-down, aggressive defensive play but they werent this "sexy, alluring, high-scoring" squad that won always on shootouts. Defense and sort of having the NBA's version of Bill Belichick (albeit more liked, well-respected, and with a few more friends) in Gregg Poppovich who could out-strategize, out-maneuver, and motivate better then most other NBA HC's in his prime.
Teams like San Antonio and later on, the mid-late 2010's Golden State Warriors LeBron James doesn't have 7,8, or 9 NBA rings on his fingers right now.
