I often expressed my hatred for the 3-4 defense to fellow coaches when I was a high school football coach. The more I learned about it, the more I hated it. The problem was mainly in the fact that it is so difficult to run a true 3-4 with high school players because of their physical limitations. The other big factor was that most teams in high school rely heavily on the run, and without 3-4 personnel, you will struggle to stop the run unless you abandon the 3-4 for pretty much a 5-2 type defense.
At UGA next season, I feel we do have the right players to make Grantham's style work! The athleticism, size, and strength are all there. The only question that remains is if we can put it all together, and from what I am hearing and seeing this spring...YES WE CAN!
All this being said, I found a pretty interesting and informative article online today that breaks down most aspects of the 3-4 and even converting from a 4-3.
