The San Antonio Spurs and the organization’s two stalwarts, Tim Duncan and Gregg Popovich, are coming off a fifth championship and are poised for another title run next season – provided Duncan doesn’t retire. With five championships in a 15-year period, the Spurs have made a claim to be considered a dynasty. However, some people – most notably Phil Jackson – would disagree because the Spurs haven’t won consecutive titles. Jackson won three consecutive championships on three separate occasions (1991-93, 96-98, 2000-2002).
