Celtics general manager Danny Ainge regrets not re-signing Tony Allen.

"I would have fought harder to bring Tony Allen back," Ainge said. "We tried to sign Tony, we tried to come within our rules of staying in our two-year program. I think that Tony would have helped us.

"We offered Tony a two-year deal out of the gate, but then when Memphis showed him some love and he started thinking about the idea of more playing time ... Then, he wanted a change of scenery."
