"He bailed on me again this time," said Rondo of Bryant, after scoring 11 points with 11 assists and eight rebounds against the Lakers.
The pair went for breakfast together in December in Boston, before Rondo's trade to Dallas, which only fueled rumors that Rondo would be a Lakers' free-agent target this summer.
"I left a couple of voice mails, but he didn't respond" said Rondo, noting they would have to hook up some other time.
How about in July (when the Lakers can officially recruit him)?
"I don't know," answered Rondo. "I might change my number by then, so we'll see."
Rondo is earning $12.9 million with the Mavericks, the seventh-seeded team in the Western Conference.
Bryant is sidelined with a shoulder injury.
