"Consider them done deals," one source close to the talks told ESPN.com.
ESPN.com reported Monday that Lopez and Young would come to terms with the Nets in the first few hours of free agency, although the deals can't be officially signed until July 9, when a leaguewide moratorium on player business is lifted.
Lopez will get a three-year deal in the $60 million range, while Young will get a four-year deal in the $50 million range, sources said.
Lopez's deal is likely to include a wrinkle or two to provide some financial insulation to give the Nets a measure of protection in the event Lopez misses more significant time due to the foot injuries that have plagued his career.
Nets general manager Billy King has been open about his team's hopes of re-signing both Lopez and Young.
Lopez, who has spent his entire career with the Nets despite being involved in trade talks on numerous occasions, averaged 17.2 points, 7.4 rebounds and 1.8 blocks per game last season. He started slow coming off foot and ankle surgery, but eventually regained his top form under new Nets coach Lionel Hollins and carried Brooklyn into the playoffs after the All-Star break.
Lopez also worked well in tandem with Young, who was acquired at the trade deadline fromMinnesotain exchange for Kevin Garnett. In 28 games with the Nets, Young averaged 13.8 points while shooting 49.5 percent from the field.
