  Quark models taking into account the dynamical effects of hadronic decay
often produce very different predictions for mass shifts in the hadron
spectrum. The consequences for meson spectroscopy can be dramatic and
completely obscure the underlying confining force. Recent unquenched lattice
calculations of mesonic resonances that also include meson-meson interpolators
provide a touchstone for such models, despite the present limitations in
applicability. On the experimental side, the $\rho(770)$ meson and its several
observed radial recurrences are a fertile testing ground for both quark models
and lattice computations. Here we apply a unitarised quark model that has been
successful in the description of many enigmatic mesons to these vector $\rho$
resonances and the corresponding $P$-wave $\pi\pi$ phase shifts. This work is
in progress, with encouraging preliminary results.
