The San Antonio Spurs had a “superteam” that didn’t come together with free-agent signings, which had Tim Duncan, Tony Parker and Manu Ginobili in their primes. They added Kawhi Leonard in the 2011 NBA Draft, and won the 2014 NBA championship with him.
However, the times may be changing. The Golden State Warriors and Cleveland Cavaliers have dominated the NBA for three years, being known as “superteams.” This became the case with the Warriors in the 2016-17 season when they added Kevin Durant. The Cavs have had a core of LeBron James, Kevin Love, and Kyrie Irving for all three of these years.
