Five reasons why the San Antonio Spurs' dynasty is still alive

#4 Gregg Popovich's ability to reinvent and retool the Spurs roster

Pop remains the greatest coach in the NBA currently and one of the best of all-time

Recognised as the best coach in the NBA for his longevity and the continued success and evolution of his teams, Gregg Popovich is a big reason why the San Antonio Spurs' dynasty is still alive.

With five Championships in 21 seasons as head coach of San Antonio, it is his ability to constantly reinvent his teams and adjust to the situation that has helped him become a legendary coach.

Whether it was drafting Tim Duncan in 1998, Tony Parker in 2001 or trading George Hill for the draft rights to Kawhi Leonard, Popovich has been calculated and ruthless in his moves, helping establish the Spurs dynasty.

He converted his team from a traditional, two big team that hung their hats on defense to an extremely efficient offensive unit, relying on ball movement and outside shooting to complement their inside game.

The 68-year-old maverick has now implemented another change in the system, making them more of a small ball team that will rely on fluid movement and selfless basketball, in addition to smothering defense, to outsmart their opponents.

A testament to that approach is the fact that the roster has only four genuine big men, with LaMarcus Aldridge leading the charge, and Pau Gasol, Joffrey Lauvergne and Davis Bertrans providing support off the bench.
