WALTHAM — After passing a physical that finalized a two-year free agent deal, Jermaine O’Neal said that Rajon Rondo was the most important person to sell him on the value of signing with the Celtics.

“I had some great conversations with Doc [Rivers], Danny [Ainge] and Paul [Pierce] and Rondo, and Rondo actually was probably the guy who sold it the most, and I had great conversations with all four guys but he really helped me understand where my fit would be,” O’Neal said. “I’m not concerned about shots, I’m not concerned about minutes. I’m not concerned about anything but winning. At the end of the day, you can build up individual goals, but your validation is whether you win or not.”

O’Neal also gave credit to Rasheed Wallace, who also sold him on the quality of the organization. O’Neal said he texted Wallace to see if he could convince him to come out of retirement. He said he hadn’t heard back but would be getting together with him soon.
