With 15 schollies, it doesn't hurt to gamble on a "project", particularly a "big", that is athletic. I think you have to be more careful on the boys side, as they only have 13 schollies to give.
Like Syb has said, there is so little information out there on Gibbs, that it makes her interesting.
Anymore the big programs focus on the AAU programs, and if you don't play on those teams, I think you can slip through the crack. Maybe that is the case with Felisha.
In any event, you can only really play 8-10 kids, and so you have room for a kid that might take a year or two to help.
