Football Defense - Breaking Down the 4-3

[Pezlo1921]

Are you coach Phillip Blackwell from Perry Hall? I attended a Glazier camp a cpl years ago and sat in on your seminar. I was thinking about it for the past few days and I remember you saying to email you if we wanted to learn more about it but I must have not wrote it down that day...i actually remembered most of these signals but would like more info, would you still be able to help? Thanks
