Can Barea breathe life into Mavs?

DALLAS -- J.J. Barea is the Mavs' best player at the moment.

Barea, who is getting the backup point guard minutes this half while rookie Roddy Beaubois watches, has seven points in the first five-plus minutes of the fourth quarter. The odds are still stacked against the Mavs, who are down 13, but Barea has at least given them a chance.

But Barea, a DNP-CD in Memphis, isn't a player who can carry a team against a quality opponent. The cavalry needs to arrive quickly for the home team.
