Ivica Zubac spent the summer improving his conditioning for Indiana's fast-paced offence, AP reports on NBA.com. He returned to the United States early to train with teammates and adjust to Tyrese Haliburton's quick decisions. The Pacers expect his screening, rebounding and defence to complement their system. Zubac played only five Indiana games last season after joining the club. Their developing partnership remains a preparation story, with its effectiveness to be tested in competition.
