No it wasn't.
The Illinois game was the same $h!t we saw in the previous 3 seasons, and it is the same $h!t we have seen in the past two months. Sometimes these performances have been against top 10 teams, sometimes they have been against crap teams. But we always find new ways to make dumb mistakes and we never close the deal. We've lost more games in this exact manner than we have won in any manner. And every time we find ourselves in a "must win game" or "the most important game of Frost's career" or "chance to make a big statement," we fail. Every. Damn. Time.
The Illinois game is not a head scratcher, it is the norm. In fact, the Illinois game is the quintessential Scott Frost coached game at Nebraska.
