I think you might be underselling Carrington and Payne. Payne will probably start ahead of Fox, who would be much better off the bench. He is limited offensively as a shooter - an athlete who will be able to guard, rebound, etc. - nice to bring off the bench. Someone else may come in but right now Payne, Ihnen, Battle a nice trio because both Ihnen and Battle will stretch the floor and go to basket - Ihnen will look much better with new staff.
Carrington can guard people and shoots the ball really well. I wouldn't put him to the bench right away, and we don't really know anything about Henley. Will be interesting to see who else they bring on for the perimeter. And, Ben, and most college coaches, don't think 1-5 anymore. It's funny to me that fans still label players that way when almost no one coaching does that anymore.
