  In this paper we present predictions for thermodynamic and transport
properties of a BCS Bose-Einstein crossover theory, below Tc, which theory
satisfies the reasonable constraints that it yield (i) the Leggett ground state
and (ii) BCS theory at weak coupling and all temperatures. The nature of the
strong coupling limit is inferred, along with the behavior of the Knight shift,
superfluid density, and specific heat. Comparisons with existing data on short
coherence length superconductors, such as organic and high Tc systems, are
presented, which provide some support for the present picture.
