Place players, blocking sleds and dummies on the full field and write up route trees, blitz pickup or 7-on-7 drills ready to print.
American football practice is built around two units working against each other β a route tree only makes sense against coverage, pass protection only makes sense against a pass rush β so the designer keeps offense and defense as distinct groups and lets you scale a drill from a 7-on-7 passing period up to a full team period at 11-on-11.
