In the old days if a program was purchased the new owners - assuming they were hockey guys - would enlist one parent / coach to lead the flagship team for visibility and credibility. Usually it was an ex-NHL'er and his kid and a couple of the kid's ringer buddies. They would walk all over local competition and then do a couple of the bigger, national type tournaments and that got the talk going locally and parents followed.
The BA approach is a bit different. Build a respected program though developing players, attract the older kids and land them some sweet D-I / junior hockey deals and the parents and younger kids will follow based on development and results without regard to who is actually sitting on the bench every week.
