Jae Crowder, Bernard James and Shane Larkin headline a list of 13 players who are on the Dallas Mavericks' summer league roster.

In 78 games as a rookie last season -- which includes 16 starts -- Crowder averaged five points, 2.4 rebounds and 1.2 assists in 17.3 minutes per contest. He also shot 38.4 percent from the field and 32.8 percent from three-point range.

James, meanwhile, had 11 starts and played in 46 games last year as a rookie and averaged 2.8 points and 2.8 rebounds while shooting 51.5 percent from the floor.

Larkin was the 18th player chosen in last month's NBA Draft and is expected to compete for valuable minutes at point guard this season.

Monte Mathis will coach the Mavs' team and will be assisted by Kaleb Canales, Darrell Armstrong, Mike Shedd and Mike Weinar.
