“I love what you’re doing at X&O Labs. I’m all for it. I love the research you’re getting out, it’s all very good stuff.”
Chris Ash,
Defensive Coordinator, University of Arkansas
This study took over six-months to compile the research data, conduct interviews with coaches like Bud Foster and watch hundreds-of-hours of game film from schools like Virginia Tech, James Madison and some of the top high school programs in the country. What we found in our research was nothing short of powerful. Our research identified new, emerging trends in the 4-2-5 defense – and our re-examination of the established concepts of this defense identified the best teaching methods, strategies and drills.
This is no small study. It totals over 23,000 words and includes 116 diagrams and 28 videos (featuring game film and drills). We’ve released The 4-2-5 Defense Study into four cases:
This report closely examines Bud Foster’s Virginia Tech defense. Plus, we cover everything from formation calls to the “Maintaining the Box” theory (and just about everything in between). Here’s just a small sample of what else you’ll see in this report:

Virginia Tech’s Defensive Coordinator, Bud Foster, contributed significantly to The 4-2-5 Defense Study.
When we first compiled our research for this project, we received a lot of write-in questions from our readers. So we decided to go straight to the source of some of the best 4-2-5 minds in coaching. This is only a very small fraction of what these guys told us:

“We’re enjoying what you’ve [X&O Labs] been doing for the coaching community. Keep up the good work.”

Offensive Coordinator, Atlanta Falcons
“The 4-2-5 Study is outstanding! We are a 3-4/4-2-5 hybrid defense and this special report was an excellent road map to help us mainstream our blitz games from both packages without changing terminology. Excellent report!”

This report reveals the most intriguing aspects of our research – our data identified the best formations to pressure and the best players to pressure with. Now this report isn’t all research data. We also included much more, such as:
Again, that was just a small sample of all that is included in The 4-2-5 Defense Study.

“I enjoyed reading the 4-2-5 Defense Study. We’re a multiple 4-3 defense meaning sometimes we are 4-2-5 or in our alignment. All of the variations of coverages featured in the 4-2-5 Defense Study were very interesting and extremely helpful.”
Coach Nick Ware

This study has already helped me as a high school defensive coordinator.
