It's a bit disappointing that one of the biggest changes in history is getting such little (zero, actually) discussion here.
It is a good bet that the FHSAA will be inept at enforcing the rules around this. Only select programs will be able to capitalize on it THIS year. But, in future years, we will see well-funded programs develop "collectives" or something like them, bring in a higher profile coach than previously possible, and poach players from all over. It probably won't be driven so much by huge fan support, but by a smaller number of wealthy people who want their hand or name in bringing home hardware to the program. That sort of thing has already happened at St. Frances Academy in Baltimore. SFA had really one major investor (the current head coach of UNC-Charlotte) that saved the school from closing with large investments. SFA regularly recruits players from other states, including Florida. SFA is not a member of any state association, so it is literally 100% unregulated, which won't be the case for Florida schools. But, now, more schools will be able to offer an approximation of what SFA has been doing.
