Mike McCarthy was reluctant to play recently signed halfback Dimitri Nance in his first three games with the Packers because he didn?t know the Packers? offense well enough, but Nance appears to have a good enough grasp to play in most game situations if called upon this week at Washington. Nance, signed off Atlanta?s practice squad after Week 1, had two carries for six yards in the Packers? blowout win over Buffalo, then was inactive the following week at Chicago and played only on special teams last week against Detroit. John Kuhn and Brandon Jackson are the only other halfbacks on the roster, and the Packers figure to take a look at Nance soon to see if he can contribute or even become their primary halfback.
