I live in Plantation now but grew up in West Palm Beach and went to high school in Riviera Beach. I have not followed recruiting in the area closely in a long time.
However,
@RattlerCane305's post above is correct, and I will add a few things here.
Coach Daniels can't be replaced at Dwyer, end of story. Riviera Beach has an INSANE concentration of good players, but just by virtue of district boundaries, they are divided between D Block, Suncoast, Gardens, and Lakes. In a given year, you will also see 3-4 Riviera Beach kids on the roster at Newman and a couple at Benjamin (Newman is a Catholic school and Benjamin is non-parochial private).
Transfer culture has long been common in Palm Beach County. It used to be common for kids from further east to transfer to GC (Damien Berry, Jessie Hester Jr, several RPB kids). There have been far fewer transfers to GC in recent years, and far more transfers out. I don't know if that's an issue of the coaches, but it sure as **** didn't happen in the late 90s, 00s, and early 2010s under Snead, Bueno, Hester, and Blackmon.
Oxbridge, a relatively new private school (Travis Homer), folded its program in recent years amidst allegations of misconduct, but is now restarting again. That could be interesting.
Palm Beach County has always been divided territory in terms of recruiting. Miami has never owned it, but neither have FSU or UF. I don't see that changing. that's also part of the reason you don't know the payers as well.
All of this being said, I don't think that the culture of the area puts as much emphasis on high school football as in the past (I graduated high school in 05, for reference). There may be others who disagree with this sentiment.
@Liberty City El is also familiar with the Riviera Beach area in particular and maybe can shed some additional detail/light on what I am saying.
