Before there were rampant transfers, that's not totally true. Yes, the MNW, CC and SR had their fair share of titles. But with the talent spread among more schools the Jacksons, NMBs, MS, CG, etc., etc. used to have decent teams (in the case of Jackson very good teams) too. What we have in large metro areas now, and I won't limit it to south Florida, as it includes Tampa Bay, Greater Orlando, Jacksonville area, etc., are stacked teams where 5 to 6 schools have 90+% of the elite talent and many of the others have a hard time winning a few games each season.
It goes without saying that this is not a model for the health of the sport at the high school level. It needs to be addressed one way or another or there will likely be mass exodus from the FHSAA tournament in the not too distant future.
I won't hold my breath.
