Agreed, the interesting thing is, the common belief is the 3-4 is more effective vs the pass and weak vs the run, but i saw a study done in 2023 in the NFL that these 1 gap 3-4 schemes were not only much better vs the pass, but actually also slightly better at stopping the run. The 1 gap system gives u gap integrity but the 3-4 alignment puts more bodies on the line. And I agree, SOLB is a must.
