I would add that if you compare CESA Columbia with CESA Greenville they are not operationally integrated. While Pearse Tormey may be the president of CESA-C, Eddie Crosby handles day to day operations. CESA Columbia exists as a local midlands club, with its own teams and coaches. While there are ties, the players, who are all Academy age, think of themselves as CESA Columbia players. They only go to Greenville for tournaments. CESA Columbia is even planning to field a u13 Select team next year, so the prediction that it would "feed" Greenville's select teams hasn't come true (yet, at least).
I agree, however, with the observation that CESA Columbia, is a "professionally run club" in the sense that it has a professional coaching staff that operates according to a coordinated coaching philosophy. I imagine that's true of several Midlands clubs, including CUFC; it really comes down to which club, and team, is the right fit for individual players.
don't know enough about SSC to say what the CESA connection will mean. However, it does not seem that SSC would necessarily go to war with the Bridge. For instance, I doubt that CUFC is threatened in the least bit by CESA-Columbia, which represnts only a small fraction of the midlands player pool.
