Broward has done slightly better than Dade in 8A. I agree with your point, but there's not that many good teams in either county, IMO.
In dade, there's 6-7: Carol City, Central, Booker T, MNW, Columbus, South Dade, and this year Palmetto.
Broward: STA, AHP, Chaminade, Gibbons, Deerfield, and they'll have another team that will be good for 1-2 years (their version of palmetto).
The rest of the teams are several tiers below and are worse than before with now being able to enroll in any school.
You can still find D1 prospects at other schools, but that doesn't always mean that they have a good team. There have been plenty of teams with a bunch of D1 kids that have sucked. This is why I always say that we have the most talent in our area, but the competition or quality of opponent that the majority of our local teams face isn't any better than most of the power states (if not worse due to the resources for coaching). For example: if STA didn't schedule those OOS and out of class teams, their schedule would be a joke.
