LINCOLN, Neb. (AP) — Nebraska's offense unveiled the top backup to quarterback Taylor Martinez and introduced a newcomer at running back whose name will be easy for fans to remember.

As for the defense, Saturday's spring game offered no comfort to fans curious to see the progress of a unit that must replace eight starters.

"The message to the team is: If we think that right now that we can just do what is required and be ready to go and be the type of football team we want to be, it's not going to happen," coach Bo Pelini said. "We have to go over and above. We have to do more than what's required."

Tommy Armstrong passed for 102 yards and a touchdown, and King Frazier ran for 64 yards and a touchdown in front of 60,174 at Memorial Stadium.

The coaching staff attempted to split the Red and White squads evenly, and the Red was officially credited with a 30-21 victory. The squads earned extra points through a couple in-game contests, which made it 32-25 on the scoreboard.

Armstrong played six series in relief of Martinez and completed 5 of 7 passes for the Red team.

The redshirt freshman's touchdown pass was a well-placed 37-yarder that hit Alonzo Moore in stride along the sideline. Pelini said after the scrimmage that Armstrong came out of the spring as Martinez's top backup.

Ron Kellogg III, the No. 2 quarterback last season, was 11 for 12 for 148 yards and a score for the White team.

Frazier, a redshirt freshman from Lee's Summit, Mo., and no relation to 1990s star quarterback Tommie Frazier, broke loose for an 18-yard run on the first play from scrimmage and proved difficult for cornerback Ciante Evans to bring down. Frazier ran around right tackle five plays later for a 1-yard touchdown.

Frazier's emergence should alleviate concern about running back depth. Ameer Abdullah, the starter, sat out with a knee injury. Imani Cross finished with 55 yards and a touchdown on seven carries for the Reds.

Martinez, who'll be entering his fourth year as the starting quarterback, was limited to two series. He hit C.J. Zimmerer with a play-action pass for a 45-yard touchdown.

Armstrong recovered from fumbling on his first play to show off a strong and mostly accurate passing arm.

Armstrong's first big play came when he hit a well-defended Brandon Reilly along the left sideline for a 32-yard gain. The second came when he connected with Moore for a touchdown to start the second half.

Kellogg directed touchdown drives on all three of his series for the White squad, finishing his day with a 17-yard pass to tight end David Sutton.

Kellogg said he had no reaction to Pelini's announcement that he would go into the fall behind Armstrong.

"I don't pay too much attention to it," he said. "Whoever can execute the best come fall time should go in. I don't really harp on that whole competition stuff. I'll do what I have to do to get our team a victory. If it's me, it's me. If it's Tommy, kudos to Tommy."

Neither Armstrong nor Frazier were made available for interviews because of Pelini's policy to not let players speak to the media until they've played in a game.

The Red and White defenses combined to allow 705 yards in an abbreviated scrimmage that employed a running clock the entire second half. Quarterbacks completed 30 of 44 passes for 409 yards. There also were lots of missed tackles and busted assignments.

Defensive coordinator John Papuchis noted that 20 of the top 22 players on his side of the ball were inexperienced and that a number of them looked nervous in front of the big crowd.

"I'll be worried if we don't maximize April, May, June, July," Papuchis said. "If we start up in the fall and pick up right where we left off today, yeah, I'll be concerned."

Mauro Bondi, the successor to kicker Brett Maher, showed plenty of leg strength on both of his field-goal tries. Aided by a 17-mph wind gusting to 33 mph, he lined a 50-yarder through the uprights. He missed to the right from 58 yards but had plenty of distance.

There were two breaks in the scrimmage for competitions whose winners accumulated points for his team.

The White team won 3-1 in something called the "compete" contest at midfield. One defender was pitted against two blockers for 15 seconds, and he would try to tackle a ball-carrier behind the blockers if he broke free. There was a 1-1 tie in a contest that had offensive lineman catching punts.
