Until last week, the Boston Bombers were the city’s only semi-pro women’s basketball team, one of more than 40 national organizations affiliated with the Women’s Blue Chip League. They held tryouts in Jamaica Plain, fostered regular player-development clinics, and maintained a summer league. They also, like any sports club, had an aggrandizing logo of cartoony power, a lit-fuse Wile E. Coyote bomb with basketball grooves.
