Players were never able to advance the ball. Instead, each player was required to toss it from where he caught it. The first team credited with advancing the ball by dribbling did so at Yale in 1897, and the official allowed for dribbling, initially only one per possession, was implemented four years later. The slam dunk, another major basketball technique, was outlawed from the 1967-1968 season until the 1976-1977 season.
