  The spectral width and sharpness of unfolded, observed GRB spectra have been
presented as a new tool to infer physical properties about GRB emission via
spectral fitting of empirical models. Following the tradition of the
'line-of-death', the spectral width has been used to rule out synchrotron
emission in a majority of GRBs. This claim is investigated via reexamination of
previously reported width measures. Then, a sample of peak-flux GRB spectra are
fit with an idealized, physical synchrotron model. It is found that many
spectra can be adequately fit by this model even when the width measures would
reject it. Thus, the results advocate for fitting a physical model to be the
sole tool for testing that model. Finally, a smoothly-broken power law is fit
to these spectra allowing for the spectral curvature to vary during the fitting
process in order to understand why the previous width measures poorly predict
the spectra. It is found that the failing of previous width measures is due to
a combination of inferring physical parameters from unfolded spectra as well as
the presence of multiple widths in the data beyond what the Band function can
model.
