Instead of saying 3-4, or 4-3, or nickel being base... I think the way to look at it is that "situational" is "base". Josh Jones is a hybrid guy; Jones in Atlanta; etc...
Smallish LB's, big safeties, odd fronts... I don't think there is a real base anymore - except for Capers, who a couple of years ago ran that nauseating 2-4 that max loved so much a sickeningly ineffective 80% of the time.
Max, let it go... your heroes (dunderdummy and Randall) have finally been booted out of Green Bay...
And the peasants rejoiced...
