The Sacramento Kings expressed strong interest in point guard Rajon Rondo during a phone call at the start of the free-agent period, league sources told Yahoo Sports. Rondo received a phone call from Kings president of basketball operations Vlade Divac after the NBA's free-agent market began at 12:01 a.m. ET Wednesday. Divac did not offer a contract to Rondo, but did invite him to visit Sacramento for face-to-face talks and a tour, a source said.
