There might be some confusion about what hypothetical the OP is posing then. Is this a "hindsight is 20/20 post facto South Florida all star team" or is he saying if we ONLY recruited South Florida and hit on most of our targets?
And I agree that the South Florida QB stereotype is overplayed...
You'd be more that deficient annually at QB, OL, DT and K.
And I say that as someone that'll fight the clowns in Texas, California, Louisiana and Georgia when they claim to have equal or better high school football.
