This is the part that concerns me. It's very difficult to adjust to breaking the rules, or bending them just short of breaking. How do you adjust to the prairie dog offensive linemen? How can you adjust to offensive linemen further than 3 yards down the field? How can you adjust to 6 men on the line, or two guys moving simultaneously? How can you adjust to getting on the line and having the coordinator in the booth relay the defensive formation down to the field? That is the worrisome part, it's not like they are adjusting to new offensive formations, or a new pass route, they are attempting to adjust to outright rule breaking while not breaking the rules themselves.
