Bo's defensive short comings in the past partciularly in 2009 were masked by talent and a guy named by Suh, the next year the secondary takes over and you still have a good defense because teams can't pass successfully on you a majority of the time, then you get to last year where you only have one guy that is great with a bunch of average joe's and you see the result. Nebraska did not have a good defense last year, the numbers and personnel show that, Bo has to be able to change his defense when need by and allow more players to see that field that he wouldn't. He keeps great athletes on the bench and won't let them go out and learn by playing, he puts out guys that aren't as athletic but know his system and last year he figured out that doesn't work, athletes are needed to make a defense successful.
this is a tricky situation.
i remember coaches always saying they didn't 'like' but could tolerate physical or hustle errors.
but the mental mistakes and not knowing that week's scheme and packages would get you benched after 1 play sometimes. if you don't know what your doing out there and are even a half foot out of position at this high of a level...it can cost you points and yardage almost every play.
but damn, watching a slow db or a soft d-lineman just plain getting beat is tough on fans, as all we see is that play on TV over and over.
coaches however watch excruciating amounts of film and i'm sure it's more difficult to watch a kid with a ton of talent be out of position play after play after play, which is what we as FANS don't see, and we are left wondering how Cassidy is playing in front of Smith.
