The ABA distinguished itself from its older counterpart with a more wide-open, flashy style of offensive play, as well as differences in rules (a 30-second shot clock – as opposed to the NBA’s 24-second clock. The ABA did switch to the 24-second shot clock for the 1975-76 seasons – and use of a three-point field goal arc. Also, the ABA used a colorful red, white and blue ball, instead of the NBA’s traditional orange ball. The ABA pioneered the now-popular slam-dunk contest at its all-star game in Denver. Legends of the old ABA include “Dr. J” Julius Erving, Rick Barry, Connie Hawkins and Larry Brown.
