LINCOLN — Marlon Lucky had his share of things to work on during the offseason.

Apparently, reading and studying was at the top of the list.

"I got into the playbook more and just got used to it," Lucky said. "This year, I'm real comfortable. I know the playbook. I got it down real good."

Lucky displayed his offensive knowledge for a second straight Saturday for Nebraska (2-0). The highly recruited sophomore from North Hollywood, Calif., topped the century mark in rushing for the first time during Nebraska's easy 56-7 victory over Nicholls State on a rainy day at Memorial Stadium.

Lucky rushed for 103 yards on a game-high 18 carries. He scored Nebraska's final touchdown of the first half on a 1-yard run.

"I was in a groove," Lucky said. "The offensive line was blocking awesome, and I took it from there."

Lucky, who only rushed for 129 yards and no touchdowns last year, heads into his homecoming game Saturday at USC with 182 rushing yards and two scores on the young season.

"Marlon's doing a great job," Nebraska quarterback Zac Taylor said. "He is playing faster than last year. You can really see it in the passing game. He knows what he's doing out there."

Does that mean Lucky has the lead in the four-headed I-back monster that is Nebraska's rushing attack?

"It's tough to say he has separated himself," Taylor said. "They're all playing well."

True. Junior Kenny Wilson rushed for 79 yards on nine carries with a touchdown, while sophomore Cody Glenn contributed 47 yards on 11 rushes and two touchdowns.

Junior Brandon Jackson had 29 yards on seven attempts as Nebraska rolled up 261 rushing yards — nine more than last week. The Huskers ran 76 offensive plays against the Nicholls State (1-1), including 50 running.

"Coach (Bill Callahan) emphasized pounding the rock," Lucky said. "That's what we did."

It's the first time Nebraska has posted back-to-back games with 200-plus rushing yards since opening the 2004 season with 363 yards against Western Illinois and 274 versus Southern Mississippi.

The Huskers' ground game set the tone early. All the yards on their opening 53-yard touchdown drive came via the ground.

Lucky had 15 of Nebraska's 28 first-half rushes. He picked up 95 yards (82 rushing, 13 receiving) in the opening 30 minutes.

"I really enjoyed watching Marlon," Callahan said. "He hits those runs, and he's getting a good feel for the offense and the running attack. I think, from what I saw today, he's setting his blocks better. His course set the blocks for those linemen's blocks today."

Despite another solid effort, Nebraska running backs coach Randy Jordan said Lucky didn't separate himself from Glenn, Jackson and Wilson.

"I think he played well," Jordan said. "There's enough offense to go around. The kids feed off each other. It keeps them on their toes."
