If I run out on 1st & 10 with personnel & keep that same personnel on the field the entire time how do I have an advantage? You saw the personnel I came out with & countered it. If your desired 11 can't stop mine that sounds like a coaching issue not safety issue.
Also you're acting like uptempo offenses are running 15-20 play drives. They're not. Again if your defense can't stay on the field 7-8 plays sound like a coaching issue not safety issue. Also if you want to substitute get a stop. Teams usually go fast after 1st downs. STOP SOMEBODY!!
