Out of all the highlights I just watched on this kid, not one of these defensive lineman stayed low like you are suppose to. What are the coaches teaching these kids? Is this like 1A or 2A High School football?
The simple solution would be to run a Gap-Air-Mirror defense with your four defensive linemen penetrating the A and B gaps in four point stances. Then let "Will" and "Sam" contain the outside edges just in case they run a misdirection with another back. "Mike" could help clean up after the D-Line submarines. Everyone knows the lowest man wins on the line!
It is nice though to see a kid who usually gets automatically thrown on the line, get a chance to run the ball. His size makes Jerome Bettis look like Darren Sproles...
