Australian center Andrew Bogut signed a free agent contract Thursday with the defending champion Cleveland Cavaliers, who he opposed in the past two NBA Finals while playing for Golden State. The 32-year-old 7-footer (2.13m) is in his 12th NBA campaign after being the top overall pick in the 2005 NBA Draft and his arrival gives the Cavaliers' lineup another key inside player with championship experience. Bogut was traded from Golden State to Dallas after last season to make salary cap room on the Warriors for the signing of star forward Kevin Durant, now sidelined with a left knee injury.
