Maybe it’s because he doesn’t like dealing in speculation. Maybe it’s because, with an infant at home, he understandably already had his mind fixed on the All-Star break. Whatever the case, Justin Holiday didn’t offer much late Wednesday when asked how he’d respond if his role is limited in the Bulls’ 25 remaining games following the break. Management has made clear it wants to see playing time for young players such as Cameron Payne, Noah Vonleh, Paul Zipser and Cristiano Felicio. And coach Fred Hoiberg said one of his and his staff’s projects over the break is figuring out a consistent playing rotation featuring new roles. Given that playing Zach LaVine, Kris Dunn and Lauri Markkanen remains a priority since the core only has appeared in four games together, there aren’t enough minutes for everybody. “I have to see when that time comes what they decide,” Holiday said. “They’re employers. They make the calls. I just do my job when I’m called upon.” The most likely victims of the youth movement are Holiday and Robin Lopez, for multiple reasons. The biggest may be that they’re not only established players but they’re good ones. And with the Bulls hitting the break with the league’s eighth-worst record, three games ahead of the last-place Hawks, ping-pong balls are dwindling.
