You don't need hours and hours of drills with coaches or film-room discussion to know the basics of how to be a great pass rusher. Ziggy picked it up in less than a season.
If you think the problem with our pass rush is that Kaufusi (son of a coach) and Rowley are not getting coached properly or not enough, you need to sit down and think about how difficult it really is to pass rush. These guys are either too dumb to understand how to do it or just too slow to implement it. I'd like to think it's the latter.
