The NBA is a copycat league. What the most successful teams are doing will often dictate what the rest of the league decides to do.
For a long time, you had to have a twin towers duo. Dual bigs were all the rage for years in the NBA. Having extra size in the front court was a must to win on the largest stage.
Then, twin towers went out of fashion. Suddenly, teams were playing small and fast. For a while, it looked like the twin towers model was dead.
Fashion is cyclical. Twin towers are back. Now, teams love playing dual bigs.
In the modern context, having a jumbo-sized 4 with the versatility to guard the perimeter is trending.
Could the San Antonio Spurs put their new twin towers together by acquiring Kristaps Porzingis of the Washington Wizards?
