  We extend the physics case for a new high-energy, ultra-high statistics
neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to
address a variety of issues including precision QCD measurements, extraction of
structure functions, and the derived Parton Distribution Functions (PDFs). This
experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep
Inelastic Scattering (DIS) events which is over two orders of magnitude larger
than past samples. We outline an innovative method for fitting the structure
functions using a parameterized energy shift which yields reduced systematic
uncertainties. High statistics measurements, in combination with improved
systematics, will enable NuSOnG to perform discerning tests of fundamental
Standard Model parameters as we search for deviations which may hint of "Beyond
the Standard Model" physics.
