"Black Shirts" have become a weird distraction for several years now, and it's high time they just go away - it's not 1995 anymore.
Black Shirts separate the team in an unproductive way; fielding an amazing lights out defense should simply be our standard, and not something to make a big deal out of.
Look at Iowa's defense the last several years - one of the best statistically speaking over the last decade, and they just go out and get their business done with zero hype. That's actually a good model for how our D should operate going forward.
