Pretty much a lot of the teams that are already successful in their region (even though many of them have benefitted from transfers as well).
Carol City, MNW, BTW & Central, would all still be powerhouse programs.
Teams like Norland, Jackson, probably Killian & some Homestead/ South Dade area squads would probably benefit as well.
Dillard, Coco Creek, Blanche Ely, Boyd, Deerfield & other Broward schools like that would be drastically different if those type of transfer rules were implemented & they got to keep more of their homegrown kids.
It would definitely affect a school like Oxbridge, in terms of the top level talent they have every year.
Pahokee, PB Lakes, Gardens etc, would benefit both positively & negatively.
Southridge & Colombus probably wouldn't have as much talent as they do either.
I'm gonna say a school and some people are gonna think I'm crazy when I mention it. Springs, yes, Miami Springs. Of course Springs has benefited from re-zoning that relieved overcrowding at Jackson & the West since back in the late 70's(when my mom started school). The majority of its athletes come from the small western section of Brown Sub/Liberty City(Gladeview) and Seminola. I'm talkin MLK park, the Tree Bar, 46 Graveyard, Turf Motel, the Boxing Gym... Main problem they've always had is keeping the guys that are zoned there(myself included, I only attended for a week, never played for them). The one time I remember everyone staying was back in '94. They had the best defense in the state, arguably the country. They went 12-1, losing 14-6 in the State Semis to Southridge who won it all. Held the Davis Bros. to 120 yards combined. That Ridge team used to have 21 on the board during pre-game stretching. Southridge went on to score a still-standing title game record of 69 points. For example, I grew up with & attended Springs Middle with four dudes that made it to the NFL(3 of them are Canes as well),Willis, Nuke Jenkins, Javon Nanton and Zack Ville. Out of the 4, Javon Nanton was the only one who stayed at Springs all 4 years. Willis was gone by his junior year, Nuke left the same week I did, and Big Zack went straight to the West. From back in the days with Lomas Brown, Freddie Miles, and T.Y. Hilton's pops to now, that school has had some major talent come through there. El, I know you remember Ben Jones from the MNW 8. He came from Springs. Tommy Streeter & Brandon Harris are also guys from the area.
