I think Frost should just do a complete reset. Nobody gets them until the defense is a top 10 defense (obviously wouldn't happen this year). Actually play like the blackshirts of old. That way it would actually mean something. Who cares about a black jersey when your defense has more holes in it than a spaghetti strainer.
Bo kind of did that, but then every time he handed them out because the defense had "arrived" or whatever, they would play like crap again.
We've had this discussion so many times that I made a spreadsheet in 2013 about how Bo handled the Blackshirts. I'm missing two years from the Pelini Era and I'm not interested in going back and adding 2013 and 2014 to this, but the idea that they have to "earn" them on the field doesn't hold water.
In 2008 Bo waited until after the 10th game of the season to hand out the Blackshirts. We were 6-4 in those games, giving up an average of 29 points. He gave them out after the Kansas game, where the defense gave up 35 points and 422 yards. The team went 3-0 after that, giving up an average 27 points per game.
In 2009 Bo gave them out after the sixth game, Texas Tech, when the defense allowed 259 yards but 31 points. The team was 4-2 and giving up an average of 12 points per game. They went 6-2 after that, and averaged 9 points per game.
In 2010 Bo gave them out after the fourth game when the defense held South Dakota State to 3 points and 236 yards. The team was 4-0 and giving up an average of 13 points per game. After the Blackshirts were handed out, they went 6-4 and gave up an average of 19 points per game.
In 2011 Bo waited until the eighth game of the season, after they held Michigan State to 3 points and 187 yards of offense. The team was 7-1. The very next game was Northwestern, and the defense gave up 28 points and 468 yards of offense in a loss. They finished 2-3 after the Blackshirts were handed out, and gave up an average of two points more per game.
2012 was similar. Bo waited until the eighth game, Michigan, whom they held to 9 points and 188 yards. They were 6-2 and gave up an average of 25 points per game. They finished 4-2 and gave up 31 points per game after the Blackshirts were handed out.
In Bo's first five years the team had a .750 winning percentage before he handed out the Blackshirts. After the Blackshirts were handed out, that winning percentage dropped to .656 and points per game went up an average of two points per game.
This whole "earn it" thing is nonsense. The defense doesn't play better after they're handed out, and it has never meant that the defense has "arrived" at any kind of better stage of play. They seem to regress after the Blackshirts are handed out during the season.
