I expect Durham to provide a lot more production. He is just more gifted and should be completely healed.
I have read that Burns is just not able to play above the rim but that he is a scrapper. I don't expect to see him a lot. I hope he can convince the staff with his play to redshirt Doherty though.
Doherty is a real wild card. I really wanted to save his scholie for this year but Brey really liked him. It is exciting. I don't think he is 18 yet. I hope he grow another inch or two.
