  Concepts underlying the Enskog kinetic theory of hard-spheres are applied to
include short-range correlation effects in a model for transport coefficients
of strongly coupled plasmas. The approach is based on an extension of the
effective potential transport theory [S.~D.~Baalrud and J.~Daligault,
Phys.~Rev.~Lett.~{\bf 110}, 235001 (2013)] to include an exclusion radius
surrounding individual charged particles that is associated with Coulomb
repulsion. This is obtained by analogy with the finite size of hard spheres in
Enskog's theory. Predictions for the self-diffusion and shear viscosity
coefficients of the one-component plasma are tested against molecular dynamics
simulations. The theory is found to accurately capture the kinetic
contributions to the transport coefficients, but not the potential
contributions that arise at very strong coupling ($\Gamma \gtrsim 30$).
Considerations related to a first-principles generalization of Enskog's kinetic
equation to continuous potentials are also discussed.
