The mad scramble for NBA free agents can begin as early as next week. It will help determine the makeup of the league's elite for this year's short 50-game season and for years to come. This time, however, teams with the fewest free agents may have a distinct advantage because of the short practice time allowed between the start of training camp next Monday and the start of the regular season two weeks later. The teams with the most veterans signed: the Indiana Pacers and Utah Jazz who should have a leg up during the shortened 1999 season.
