Nebraska did it again. For the second straight week and fourth time this season, the Cornhuskers (No. 16 BCS, No. 18 AP) overcame a double-digit, second-half deficit to win a football game. This time they came from 14 points down to beat Penn State 32-23 on Saturday, with Taylor Martinez throwing a 5-yard touchdown pass to Jamal Turner early in the fourth quarter for Nebraska's first lead.
