What Offense are you Running? What worked for you and what didn't? Is your 6-3 Jack Gregory's Verison or different one?
A youth spread mainly of my own design (though I based it on another coaches work). My HC is running it this year and he doesn't do it exactly how I would do it.
He often keeps the slots in tight, which I would almost never do. He has more blocking assignments then I care for. (I included them in my playbook, but I wouldn't use them all at youth level). He calls way more traps then I would. I also would do my handoffs and fakes different. He has his own philosophies and that's fine.
My defense is a 6-3 of my own design. Kind of a 6-1/6-3 hybrid. It started years ago as a 6-2 with a FS, and I just abandoned the FS and changed the assignments.
It is probably similar to Jack's. I have never read his. From reading some of the threads it sounds like many of the assignments are similar, but not all.
I gave JJ's 33 Stack a go this season, and I couldn't make it work to my liking. So I switched back to my defense last week which put us behind because all the techs are different.
I couldn't make the zone work without LB's dropping underneath, and I faced a team pre-season that could pass and block very well and they drove up and down the field on me in a scrimmage. It just wasn't for me. Other people on here seem to have success with it so don't want to bash it.
