As Rajon Rondo continues to rehab from a partially torn anterior cruciate ligament injury he suffered in late January trade speculation involving the All-Star point guard will continue to have a life — possibly up to the trade deadline next year. The Celtics are rebuilding after the departures of Kevin Garnett Paul Pierce and Jason Terry. Coach Doc Rivers left to coach the Los Angeles Clippers. Rondo’s future in Boston depends on his health and relationship with rookie coach Brad Stevens. The former Butler coach hoped to build a bond with Rondo to keep his interest in the organization. However there will be many suitors for Rondo who averaged 13.7 points 11.1 assists and 1.8 steals if he wants out. The Pistons could be one of the teams interested in acquiring him even after acquiring Brandon Jennings A story out of Boston said Celtics president Dan Ainge hopes Rondo is ready by training camp. Surrounded by a young team and rookie coach the fiery Rondo clearly would be the leader of a team that isn’t expected to make the playoffs. One factor in the Pistons’ favor is Rondo is on good terms with Josh Smith the team’s free-agent acquisition. Another factor is he’d have two big men to get the ball to in Greg Monroe and Greg Drummond. Ainge likely would wait until Rondo plays see how his relationship with Stevens develops and what offers teams would present before deciding on moving Rondo.
