The effects of giant resonance couplings on the elastic scattering of nucleons from light, spherical nuclei are examined over a wide range of incident energies (18–46 MeV). General trends in the large-angle elastic scattering data for ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ that are poorly described with the conventional optical model are qualitatively reproduced with an uncomplicated picture for the giant states. Comparison is made between this approach and earlier calculations involving giant resonances and l-dependent potentials.
