•So, are ellipticals simple to understand dynamically?  Not so clear.  We’re seeing a 2D picture of a 3D object. •In general, elliptical galaxies rotate too slowly for this to account for the flattening observed.  In other words, their ratios of rotational to random kinetic energy is too low. •If ellipticity e were due to rotation (e.g., a pure oblate rotator with an isotropic velocity distribution) then (Vrot/σ)iso ~ (e/(1-e))1/2.  Is it?
