Yeah, I suppose if you want to qualify it with a subjective term like "talented" then sure....but that varies by person, to me for example a scholarship athlete at a P5 school would be considered talented in my book.
I'd say it's a few dozen who enter the transfer portal with another school predetermined. And even then with the way class limits are those aren't always firm commitments by the new school. A great example would be with Henry T and how long that went on before it was decided. I'm sure the choice to go to Bama was already made, but Bama forced him to wait in case they needed that spot for another HS talent if they landed the right one.
