(WNFL) - The Green Bay Packers do not believe they're over-using Eddie Lacy -- not now, at least. The rookie running back leads the N-F-L in carries since he was named the full-time starter back in Week-Four. And there are no signs of that abating, as the Packers get ready to host Minnesota on Sunday. Lacy has had 157 carries since then, six more than LeSean McCoy of Philadelphia and 11 more than Marshawn Lynch of Seattle. Lacy's back-up, James Starks, has only had six carries in his last two games. You might think the Packers are concerned that Lacy will hit the proverbial "rookie wall" at some point -- but the coaches don't seem to be concerned about that right now. Running backs' coach Alex Van Pelt says he looks for signs that Lacy might be wearing down -- things like slower movement and duller foot action at practice -- but he hasn't seen them. Lacy has had occasional injury problems at college. He did have a hamstring injury at Training Camp, and he suffered a concussion in late September against Cincinnati. Since then, however, Lacy has been injury-free. Defenses have made it more of a priority to control Lacy ever since quarterback Aaron Rodgers went out with a broken collarbone November fourth. Lacy's average per carry has dropped from four-point-six yards to two-point-six over his last five games.
