In standard potential-model descriptions of the Be7(p,gamma)B8 reaction the Be7+p spectroscopic factors S appear in the cross section. We argue that the microscopic substructure effects which are represented by S are short-ranged and cannot affect the asymptotic normalization of the wave function. We believe that the standard way of describing reactions in a potential model may be incorrect and the low-energy cross section should not depend on S in the case of external capture reactions, like Be7(p,gamma)B8
