Here is a highlight reel from a team I coached in 2010 – Rogers, MN 5th Grade Panthers.
We ran a version of Jack Gregory’s 6-3 defense modified to fit our league rules of no blitzing linebackers. We saw tremendous growth in skill as the season progressed and every member of the defense contributed. We had 21 players on the team and everyone started and played at least one position and played the whole game.
