You and I traded posts a while ago on this very subject.
I agree that teams can’t copy London verbatim. However, I still wonder - can teams not aim for what DeBoer did in Kitchener/Plymouth, Vellucci in Plymouth, Kilrea in Ottawa, Todd in Peterborough? That is, having a perpetually competitive team. Granted, the latter two are older examples and may or may not be relevant anymore.
Am I out of my element by asking this question? Look at DeBoer’s Rangers from 01/02-07/08. 7 total seasons. Only 1 season under 80 points (after winning the OHL + Memorial Cup). 2 seasons 100 or more points, 4 seasons above 95 points. 6 seasons above 80 points. 2 OHL championships, 1 Memorial Cup championship. 1 Memorial Cup Finalist.
I’m just throwing this out to keep the discussion going, in a little different direction from the OP’s question, but is this unrealistic for a club to try to come close to DeBoer’s Rangers tenure? Forget about Hunter/London for a second.
