Mike Rozier's touchdown runs of 25 and 27 yards in the third quarter awakened sluggish Nebraska and the sixth-ranked Cornhuskers won a Big Eight game at Kansas yesterday, 52-0.

Nebraska (7-1, 4-0), the nation's leader in scoring, rushing and total offense, led the Jayhawks (1-5-2, 0-3-1) only 7-0 after the first quarter and held a still-tenuous 17-0 lead at halftime.

But Rozier, held out of the starting lineup for the second straight week because of a hip pointer, went 25 yards around right end on Nebraska's first possession of the second half. A fumble by Robert Mimbs was recovered by Nebraska's Allen Lyday on the Kansas 13 moments later, setting up Jeff Smith's yard plunge and with 5:55 left in the quarter, Rozier went through a big hole in the middle, cut right and put Nebraska on top, 38-0. The Cornhuskers then began sending in reserves.

Rozier's hand was cut on his last touchdown run. He left the game with 123 yards on 16 carries.

"We felt like we could come out and win this game," said Kansas nose guard Dave Mehrer. "I don't know what's wrong with us. I don't think it's lack of enthusiasm or lack of hard work.
