49ers coach Jim Harbaugh said Friday at a news conference that he was impressed with rookie running back LaMichael James all season prior to getting him active at the end of the year. James scored his first NFL touchdown in the NFC Championship Game at Atlanta. "His work ethic, No. 1, was really evident," Harbaugh said. "He was taking as many reps as he possibly could. And predominately, they were on the scout team. But, he would do it as a running back. He would do it as a receiver. And really improved his hands a great deal. And route-running ability with all the thousand reps he took on the scout team. But, just great work ethic and deep desire to improve as football player and get on the field. And he’s gotten on it from the first time he’s stepped on the field. He’s been dynamic.”
