The offense didn't put up a ton of yards, and didn't put away Penn State in the 2nd half, so people are mad. I get that.
However, the offense only had 1 turnover, and NU had a 2+ score lead for half of the game. Yes, scoring TD's in the red zone would be better, but Frost went conservative and still got FG's. Frost was playing the scoreboard. One thing Frost said coming into the game was being able to find a way to score on a big play to help out the red-zone offense. NU did that with that Betts pop-pass/jet sweep.
