While I'd prefer keeping Dual in a complementary role, I would not lose any sleep if he balked at that or got a better offer and chose to not return. He got better as the season went along no doubt, and is a plus defender and disruptor. There's more he can do and grow into entering his JR season.
I simply don't see the full range of PG ability that we desperately need to become a good team again next year. Especially with a coach that does not run a good offensive scheme and needs to rely on guys who can create.
