Youth will be served. At point guard for the Knicks. With 23 games remaining in a Knicks season going nowhere, a big part of what remains will be the development of their young point guards, rookie first-round pick Frank Ntilikina, 19, and trade-deadline acquisition Emmanuel Mudiay, 21. Throw in 25-year-old Trey Burke and there’s not a whole heckuva lot of time for veteran Jarrett Jack, who started all but the first three games of the season. Jack has heard about losing minutes. The starter’s job is just a matter of time. “Not yet but you don’t have to walk me there between the lines,” Jack said. Jeff Hornacek didn’t anoint anyone his starter, but he seems intrigued by his two 6-foot-5 guards, Mudiay and Ntilikina. It could be one guy one night, another the next. “I can’t say for sure,” Hornacek said of his starter. “We have three of those guys. Depending on how it falls out and how they play, can we fall into a rotation that works? Maybe. But it might also be a case of, ‘Hey let’s try one guy one night, another guy another night and see how they run the team.’ If we’re playing those three [young] guys, two of them will be playing off the ball quite a bit. They will handle it in our offense. They’ll still get plenty of reps.” But whoever starts, beginning with Thursday in Orlando where the Knicks hope to end their eight-game losing streak, the benefits are obvious. Start with time. “Whoever we start just the added minutes. They can learn from playing those bigger minutes,” Hornacek said. When the media entered near the end of Tuesday’s practice, Mudiay, who has played in three Knicks games without the benefit of a full practice, was aligned with the first team. “We’re trying to find the matchups that work best with the guys,” Hornacek said. And that includes Mudiay and Ntilikina together.
