  We have carried out density-matrix-renormalization group (DMRG) calculations
for the problem of one doped hole in a two-leg $t-J$ ladder. Recent studies
have concluded that exotic "Mott" physics --- arising from the projection onto
the space of no double-occupied sites --- is manifest in this model system,
leading to charge localization and a new mechanism for charge modulation. In
contrast, we show that there is no localization and that the charge density
modulation arises when the minimum in the quasiparticle dispersion moves away
from $\pi$. Although singular changes in the quasiparticle dispersion do occur
as a function of model parameters, all the DMRG results can be qualitatively
understood from a non-interacting "band-structure" perspective.
