The OP completely misses the argument. Without getting into absolutes as I’m sure somebody on CB probably has, the vast majority are not arguing we should never, ever rush only 3 and drop 8 into coverage.

It is a tool and a very effective one in a complete defensive set of tools. But using a hammer for cutting, drilling, screw driving, ratcheting, and every other job under the win seems rather stupid and not all that effective.
