Of course I made this same argument when we did have guys that could 2-gap - always hated the Jumbo 2-4. Got away with that alignment some of the time, but eventually opponents realized it would always be static, and it became very predictable where every one would be; hence, much easier to block for the run, and b/c we have 2 non-pass rushers on the DL, we couldn't generate any pressure against the pass either.
The Jumbo 2-4 should have been scrapped long before MM had to step in and put a stop to the madness.
