I have been to both scrimmages so and in my opinion and my opinion only Cassidy was more accurate than Fields. I know that Fields is the better athlete but he will probably throw more passes on rollouts because of the way he throws while Cassidy is better in the pocket. I think they both will play against Bryant and because of the way the redshirt rule works Zamot will play this year so that he gets game experience.
I heard the same thing about Cassidy. Personally, Fields has the same attributes as Joe Carbone. So if you loved Carbone, you just got him back for another 2 years. I think Cassidy would have been the better QB because of his ability to throw in the pocket and his accuracy. But what do I know anyways?
