Your habit of assuming I don't understand your point, just because it's almost always built on a faulty premise at best is even more tiring.
Especially when it's a straw man about a "legacy" defense. Not only have I never heard that phrase before you, I have never seen a single post intimate that the last 5 years of Buffalo Bills football have had anything resembling consistently solid defenses.
So the point is, all the people who never made the point you're attacking are wrong. Coolio.
