Install 8: IMFB 4-2-5 Defense vs 3-back formations

Find all of the 4-2-5 FREE articles here!

One of the first things we teach in our 4-2-5 is how to align to our 20/30 personnel Tiger formation, which is a Diamond Pistol formation.

I picked this method up from Bill Castle the legendary Lakeland High School (FL) head football coach. He wants to compete and get good at what he does in camp, spring football, and every Monday during the regular season, and so do I!
