  Motivated by the heavy fermion Fermi liquid (HFFL) features observed at
low-$T$ in the pyrochlore $LiV_{2}O_{4}$, we consider a material-specific model
that includes aspects of the local quantum chemistry, the geometrically
frustrated lattice structure, and strong correlations in a {\it single}
approach. In particular, we show how geometrical frustration (GF) gives rise to
a crossover scale, $T^{*}<<J$, the intersite (AF) exchange, below which the
metallic system shows HFFL features. Our scenario is a specific realization of
the importance of GF effects in driving HFFL behavior in $LiV_{2}O_{4}$, and
provides a natural understanding of various puzzling features observed
experimentally.
