I could imagine Duke giving him a release to transfer to Syracuse. Not that I think it will happen, but the negative feedback a school gets for not releasing kids these days, to me, it wouldn't be worth Duke saying no. It would come across as not only unfair, but very petty. Especially, since he was seriously considering Cuse before Duke swooped in at 11th hour and then recruited over him.
Does anyone know if Duke does grant a release, would that reduce the sitting out period to one year? The two years is damaging because I believe you lose two years of eligibility, which is 50% of your time.
