Using a modified Lee model for the nucleon-nucleon interaction we show the equivalence of this model to an interaction based on the quark compound bag model recently proposed by Bhasin and Gupta. It is found that their choice of the sign of the parameter coupling the hadronic to quark degrees of freedom leads to unphysical results. By investigating the model with the correct sign and more general form factors, we observe that elementary degrees of freedom in terms of the elementary particle (e.g., six-quark or dibaryon) eigenstate components of the two-nucleon system, will not be resolved by studying the on-shell behavior of the T matrix, but may be seen by studying effects that depend on the detailed structure of the two-nucleon wave function.
