Stability is overrated when you're talking about a program that hasn't won anything meaningful since the Pappy Waldorf era. You call it discipline, I call it being stuck in the past. Real defensive identity is forged through competition, not just keeping the same guys in the same chairs. We had a defensive identity back in the day with players who would have walked through a wall for their teammates, not just for a scheme. This modern obsession with "system continuity" just sounds like an excuse for not being able to recruit real difference-makers. The great defenses always had a star or two that made the whole unit better, and you don't find those guys just by staying pat.
