Thanks, I already have those. You can get them free.
I have one of Dave Cisars single wing books and I dont run the offense. If I did I would still go to him for information.
When a person buys a book we usually enjoy the help that is given in the diagnosis of what is happening if there are problems.
I also have Jacks Double wing, Jack Reeds single wing, and a host of other books.
The reason I have so many books is I am an information nut and probably will never have the experiences you have with your vast coaching expertise.
Daves books also give 2 different defenses, and practice planning and alot of other help that is needed with youth coaches who dont know anything such as myself.
The only book I would give away is Reeds book 
Thanks for being part of Clarks Dum coach site

PS: Here is a list of great SW coaches. You cannot get 95% of these "free" anywhere, but we have them all in Ed Racely's SW Library.
