Brooklyn Nets general manager Sean Marks believes his team needs star guard Kyrie Irving's full participation on the court to reach its lofty championship goals.

"We need people here that want to be here, they're selfless, that want to be part of something bigger than themselves," Marks said Wednesday, according to ESPN's Nick Friedell. "And there's an objective and there's a goal at stake here. And in order to do that, we're going to need availability from everybody."

Irving played in only 29 regular-season games for Brooklyn this past season due to New York City's COVID-19 vaccination rules. The 30-year-old has a $36-million player option for next season and is eligible for an extension.

Marks defended his decision to bring the enigmatic guard back midseason in December, saying he had no regrets about reintegrating a player of Irving's caliber.
