Coach, me and my coaches found that the less you blitz with 8-9 year olds the better they do. We got burnt almost every time that we blitzed. The less that they have to think the better. As long as our defense forced everything inside we were alright. If you blitz to much kids will be out of position to often. We would put or stronger/faster LB to the wide side of the field. I'm going to have to disagree here. I have had GREAT sucess in blitzing. It all depends on what blitz you call. I have been the Def coor for my team for the past 4 years. I teach it so they have fun.. the more fun they have the better they respond. Let me know if you guys want some help.. Send me a message And I can share some things with you.
