West Goshen Twp. >> West Chester Rustin’s revelry broke the silence seeping from Springfield’s locker room. The Knights, 4-1 winners over the Cougars in the Flyers Cup A Final, congregated in the narrow hallway from both sides, each player punctuating his entrance with a shout. They’ve been through this routine before. This was Rustin’s third consecutive title and fourth in five seasons. The newest West Chester school is an established hockey dynasty.
