Miller and Jones agreed to terms with the Cavs shortly after James announced he was returning to Cleveland and signed a two-year, $41 million contract with the club.
A 14-year veteran, Miller has played Orlando, Memphis, Minnesota, Washington and Miami. He's averaged 11.8 points, 4.6 rebounds and 2.8 assists. Miller gives the Cavs a needed outside shooting threat and a player who knows how to get open for James.
Last season, Miller connected on 46 percent (107-233) of his 3-pointers with the Grizzlies.
Jones, too, can shoot. He has made 40 percent of his career 3s and won the league's 3-point shootout at the 2011 All-Star game.
