Now that Dallas has accepted the steep financial terms for entry into the National Basketball Association, expanding the league to 23 teams for next season, the next big question concerns how the league will realign.

Alignment could be a sticky problem and that is one reason the eight-member competition committee conferred via conference telephone call yesterday to start working on it.

Norm Sonju, the managing partner of a 24-member Dallas group said Monday that his group had accepted the NBA's terms for entry into the league and that the group would send a written agreement to the NBA, accepting its terms, shortly.

The terms were set last month, after, some changes in the original agreement, and the Dallas organizers were given until March 3 to accept.

Under the now-accepted agreement, Dallas will pay $12 million, $6 million immediately and the rest over a five-year span with 10 percent interest.

Under the terms of the original agreement, reached between Sonju's group and the NBA's expansion committee before the owners met, only $1.75 million of the $12 million was due immedidately, with the remainder paid over a six-year period with no interest.

Sonju, former president of the Buffalo Braves who will serve as president and general manager of the Dallas team, said that the team's home, the new $18,000-seat Reunion Arena near downtown Dallas, will be open in mid-April, and that his organization has already started scouting and looking for a coach.

The team will be stocked with players from the existing 22 teams and from the college draft.

Under terms of the expansion agreement, Dallas will pick 11th in each round of the June 10 NBA draft.

The existing 22 teams will freeze eight players from their 11-man rosters and Dallas will pick one player from each team, giving it 22 veterans to start with.
