None. Though I am sure Gerald at times has wondered what could have been if he stayed one more year.
Kyle's situation is completely different. G was a high guaranteed pick last year in a weak draft (he got picked before any of the Heels did, just a little tidbit). This year there are a lot of underclassmen making the jump and I think Kyle simply weighed his options for a late 1st round pick vs a potential lottery next year.
