This sounds about right.
If Charlie is heading up to the booth, this allows Corwin to basically have an open audition in the role of the head coach for the season. I see all this shaking out with Weis & Tenuta up in the booth worrying about schematics, while Corwin & Co. handle the personnel and on the field matters.
It seems a little convoluted and certainly unorthodox, but it might work. Certainly seems to be an effort to maximize everybody's talents. Let's just hope it's not the coaching version of Wildcat: Navy Game Edition.
