Need help with the 4-2-5

Thanks coach, I know you are busy.
I've noticed that the S/S's run with the slots also, like your corner? I guess this would give you a man free at F/S.
I also found on this board how you run a cover 2 disguise, and a goal line out of this system.
Would you recommend me getting Jeff Walker's book on the 4-2-5?

This system looks like it came from the split-4, I have been working with the split-4 idea since I saw N.E. use the inside stunts to attack the Eagles in the Superbowl.
I was going to put it in just for that particular stunt, as a defense that people haven't seen it in years, but maybe I'll expand work on it as base.

I ran split-4 while I was at Jackson and Paxon back in the early 80's, but it was the standard one we all used in those days with a standup Sam playing the 6-7 position.

I have a question about your inside linebacker play. Back then we would have the backside inside backer step into the playside A-gap on flow away, while the playside backer would scrape to the FB action.
It was an option thing.
Do you still do that? Thanks for your help BattleAxBill

Tiger One,

How do you play your disguised cover 2 out of your 4-4 look?

thanks
