Silver gets adviser

Gen. Martin Dempsey, the recently retired chairman of the Joint Chiefs of Staff, has been appointed

a special adviser to NBA Commissioner Adam Silver. The league said Friday that Dempsey, the highest-ranking U.S. military officer for the past four years, will participate in NBA functions and serve as chairman of the newly formed Jr. NBA Leadership Council. His position begins Jan. 1, 2016. Dempsey worked closely with the NBA through the league’s Hoops for Troops program, which conducted basketball clinics and health seminars on military bases throughout the country. Among Dempsey’s roles, he will take part in the NBA’s overseas exhibition games and its All-Star weekend, and participate in some league meetings.

The Milwaukee Bucks have locked up big man John Henson on a four-year extension worth $44 million, a person with knowledge of the deal told The Associated Press. The contract was agreed upon Friday morning and could reach $48 million with incentives. The person spoke on condition of anonymity because an official announcement has not been made. Henson, 24, averaged 7.0 points, 4.7 rebounds and 2.0 blocks in 18 minutes per game last season. But his playing time increased in the playoffs and the Bucks value the defensive presence he brings in the paint and his ability to guard multiple positions.

Forward Tristan Thompson of the Cleveland Cavaliers has declined to sign a one-year, $6.8 million qualifying offer for this season and remains a restricted free agent. Thompson had until 11:59 p.m. Thursday to accept the offer. The elite rebounder and the defending Eastern Conference champions remain apart on a long-term contract. Thompson was a key contributor during Cleveland’s run to the NBA Finals last season, filling in when starter Kevin Love dislocated his shoulder. Thompson and his representatives believe he deserves a maximum contract. The Cavs value Thompson, but aren’t willing to go beyond what they’re comfortable offering. Twice in the past few days LeBron James said he was confident the sides could reach a longterm deal. James is also represented by Thompson’s agent, Rich Paul.
