yes, i think (hope) brown is auditioning to be next year's OC, not next year's HC. i assume that if we hire an OC to be HC they will want to call their own plays but i don't think it's beyond the realm of possibility that they are impressed with what brown does the rest of the way and keeps him as the play caller. i also think if the offense looks competent the rest of the way it does expand the pool to defensive guys.
