The Seattle Sonics have let Andre Brown walk as a free agent as he has signed on to play for the Memphis Grizzlies.  Brown played in 38 games (0 starts) as a rookie last season for the Sonics and he averaged 7.1 minutes, 2.4 points, 1.9 rebounds and 0.1 assists per game.  He shot 56.8% from the floor and 60% from the free throw line.  The Sonics may regret letting Brown walk because he played well when given a chance as a rookie last year.
