As a coach who ran the 5-2 defense for my 12-13 year old....having lost last year in to champ. game to a wishbone option team, ive decided to install the 3-3-5 defense. I must say this a very good defense to run if you know what your doing....ive been to the best clinics that teachs this Tulsa and West Virgina both uses it and thier clinics were good. Anyone agree with the change of defense?? Anyone uses the 3-3-5??
