This D can't create turnovers, can't tackle, can't get off the field. I don't know what you do in this case, but there's no way you can look at Guidry and think "He's doing everything possible to fix this". SIMPLIFY THE SCHEME. I don't care if you have to go straight man across the board, or you just tell people "We're going zone, just stay in your spot"
PS, one Pick6 doesn't change how bad this D is.
