I thought they had more than they needed.
No. They need to renounce one of Sullinger or Zeller, or have signed letters from Zizic and Yabousele that they will stay in Europe for the season. To my understanding, none of those (except maybe Zizic), has occurred. As of yesterday it sounded like Yab still had a chance to make the team. Also, in the case where the two draft picks say they're staying overseas, John Holland also needs to be officially released.
