Green, I'm not convinced that Ridley is that much less talented than other CL schools, or that the talent in the Central is outstanding. A lot of very good HS players, but outside of the Haverford WR and Paoletti, there may not be a IA or FCS player in that league this past year. Springfield is the perfect example of just having hard workers and very good (but not exceptional talent). Ridley can match up on an annual basis.
I think a lot of the CL success comes down to preparation. GV, Springfield, Haverford and to some extent MN do a good job of preparing in the offseason and putting kids in position to be successful. Not sure Ridley's staff is at the same level yet. They had to replace Waller, Batty, Schnell, Thompson, and Bowden when they all basically left together.
