CHARLESTON, S.C. — As the Knicks have worked their way through the start of training camp at The Citadel, the attention — rightfully so — has been on the stars and starters. Karl-Anthony Towns arrives as the last piece in the building of a team regarded as a championship contender.

The Knicks sacrificed important pieces to get Towns, the cost of doing business while chasing stars. And while they have put together one of the best starting lineups in the NBA, the Knicks have questions surrounding a strong suit of last season’s squad — depth.

A week ago, Josh Hart and Donte DiVincenzo seemed bound to lead the second unit — roles they held at the start of last season. Now the Knicks are left putting together the pieces they hope can support the starters.

With Julius Randle and DiVincenzo gone, Hart moves into the starting lineup. The Knicks will cross their fingers and hope the injury problems that cost them last season don’t surface again.

Deuce McBride steps in as the first guard off the bench. Precious Achiuwa, brought back on a one-year contract after joining the team with OG Anunoby last December, will serve as backup power forward and center. Center Mitchell Robinson could return in December/January.

Without even having played a preseason game yet, there are choices to be made, roster and rotation decisions to fall in line. Coach Tom Thibodeau has spent days praising the potential of Cam Payne (signed as a backup guard) and Landry Shamet (on an Exhibit 9 training-camp contract).

“I actually like our bench a lot,” Thibodeau said. “If you look at the things that our guys have done, and I’m not exactly sure who it might be, but Landry has been on a team that’s been at a high level, Cam has been on a team that’s won at a high level and Deuce has provided a lot for us over that time. Precious has been in a lot of big games for us. And then one of the starters is going to be there with them. So I feel that our bench is going to be a huge asset for us.”

Part of that will be the continued development of McBride and contributions from Achiuwa, both of whom stepped up last season when injuries depleted the roster.

“Whoever is coming off the bench is up to Coach,” McBride said. “I feel like we have a lot of guys who can step in and do a lot of different things. We’ve been working all summer, so I feel like we have a really good group of guys.”

With versatile starters in Hart, Anunoby and Mikal Bridges, Thibodeau figured to have at least one of them on the court with the second unit. The defensive ability of those players, as well as McBride and Robinson, gives the Knicks a defensive grouping that plays into Thibodeau’s style.

“I think defensively we can become a monster,” Achiuwa said. “Looking at guys like myself, OG, high defensive-minded players. Defensively we can take the life out of teams. I think we can bank on that to win games.”

Part of what the Knicks are counting on as they make their way with this revamped roster is that there is familiarity.

Thibodeau coached Towns with Minnesota. Bridges, Brunson and Hart played for Villanova. Even the bench pieces fit. Shamet played for Phoenix with Bridges, who is convinced Shamet can help this team.

“Landry can shoot the ball really well, move without the ball and communicates well defensively,” Bridges said. “I’ve been around Landry for a while. Whenever we play pickup, I always want Landry on my team. He just daggers you away, he cuts, he moves off the ball so well. He’s fast. He can drive.

“He was a point guard before he got drafted and Philly made him into a spot-up shooter. He still has the ability to be a combo guard and do everything. I mean, I love Landry.”
