Rajon Rondo and Josh Smith discuss the possibility of playing on the same team again.

Rondo and Smith were teammates as Oak Hill.

"We call each other every once in a while to check up and see how one another is doing," Smith said on Sunday. "He's my best friend, especially in the NBA. We still talk all the time, and our families take vacations together. He's a very good friend."

Rondo will become a free agent in 2015.

"The conversation comes up," Smith admitted. "We always tell each other what a surreal moment that would be, for us to connect again. With the different free agencies that we have [Rondo comes off the Boston books in 2015; Smith is locked in through 2017], it could be far-fetched, but it could be possible. I tend to be an optimist."
