  In hep-lat/0701018, Creutz claims that the rooting trick used in simulations
of staggered fermions to reduce the number of tastes misses key physics
whenever the desired theory has an odd number of continuum flavors, and uses
this argument to call into question the rooting trick in general. Here we show
that his argument fails as the continuum limit is approached, and therefore
does not imply any problem for staggered simulations. We also show that the
cancellations necessary to restore unitarity in physical correlators in the
continuum limit are a straightforward consequence of the restoration of taste
symmetry.
