The NBA and National Basketball Players Association have discussed a model of 30 teams returning to reach a target goal of 72 regular-season games, sources said. The Hawks, who had 10 players participate in voluntary workouts on Memorial Day, are the league’s closest to that total with 67 games played this season. “Our guys are excited about the opportunity to get back to it,” Travis Schlenk, the Hawks’ president of basketball operations and general manager, told ESPN. “It has importance for us. We’re a young team, and because of injuries and some other things this season, we didn’t get to see them all together.
