It's Roddy B's role to lose

DALLAS -- Rick Carlisle corrected a question during his pregame chat with the media: He never said that Rodrigue Beaubois was the backup point guard.

Actions speak louder than words.

For the third consecutive game, Beaubois checked in when Jason Kidd took a breather late in the first quarter. While Carlisle won't say that Beaubois has been promoted or JJ Barea has been demoted, it's clear that the first-round pick has a chance to seize the backup point guard role.

But Ramon Sessions is giving Beaubois all he can handle and then some. Sessions has five points and an assist since Beaubois entered the game about two minutes ago.
