As a result, the observational spin parameter, $\\lambda_R$, has become one of the most popular methods of quantifying the relative importance of velocity dispersion and rotation in supporting a galaxy's inner structure. The goal of this paper is to examine the relationship between the observationally deduced $\\lambda_R$ and one of the most commonly used theoretical spin parameters in the literature, the Bullock et al.
