Safety Drills

It sounds to me like you already have a good number of drills to do with your guys if you know all the footwork, ball, and tackling drills. The only other drills would be based on the types of coverages you use and working on run support responsibilities, along with option responsibilities. Is this what you are inquiring about, types of drills to work on those things? If so, what type of defense do you run (along with coverages) and what is the run responsibility (primary support or secondary support)?
