Steve Kerr somehow kept a core of some of the NBA's biggest superstars hungry enough to make it through five straight NBA Finals, reaching the league's biggest stage for half a decade. Yet the Golden State Warriors head coach knows his toughest challenge as a coach will come during this 2019-20 season, as he takes an overhauled roster full of young talent and once again inculcates a culture of winning and commitment with the help of his veteran players.

“You coach according to your circumstances,” Kerr told Monte Poole of NBC Sports Bay Area. “We’ve got five rookies here. We’ve got a bunch of other young players. We have six guys returning, including Klay (Thompson), who can’t get on the court. That’s five returning guys on the court. We had 18 guys playing Tuesday, so it’s 13 new guys.

“I’ve got to explain stuff. I’ve got to coach.”

Kerr held his first practice on Tuesday, a 2.5-hour session that was far from what veterans like Stephen Curry and Draymond Green had seen in a while. The coach admitted the Warriors never had practices that long during the past few years, considering there was no need to teach concepts, only to execute them.

“I look at this year as a growth year,” Kerr said. “We’ve got to get a couple of these young guys to pop. We’ve got to get them to break through, so that when Klay is back at full strength next year we come back and we’ve got our core intact, with Steph, Klay, Draymond, D’Angelo and Loon. We’ve added to that core by that time. Maybe it’s Jacob. Maybe it’s Omari. Maybe it’s Paschall. Maybe it’s Alen. We don’t know.

“But the whole point of this year is to put in all the work, dedicate our time to all these young guys, maintain our culture, get them incorporated into our way of doing things.”

The 54-year-old coach will need the likes of Curry, Green, and even Klay Thompson to be an extension of his voice and help players like D'Angelo Russell and company to get acclimated to a standard of winning and the expectations, as well as the body of work that comes with being a championship-level organization. Undoubtedly, this 2019-20 season will showcase just how much Kerr is able to do with less talent and a lot of new pieces in the roster.
