We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector, and strong [ital NN] and [ital N][Delta] couplings, and demonstrate that the experimental [ital N][Delta] value is significantly higher than predicted in each case. Nevertheless the Goldberger-Treiman relation is satisfied in both sectors. Possible origins of the discrepancy of the quark model predictions with experiments are discussed.
