Finally finished the R4 Master Class. 24 pages of notes later and I can say it was absolutely fantastic! Made me question a lot of my preconceived notions!

I highly recommend the R4 system masterclass membership. It played a significant role in shaping my lens of the game of football. Any coach not familiar should take advantage of this opportunity!

I can remember sitting in on some of Dub's first clinic talks way back. Was a believer then. Coach is a man of great substance and creatively organized with his thoughts. Since we became members of the R4 system in the winter of 2016, we have broken our school's passing record in 2016, 2017, 2018 and passed 2000 yards passing in 2019 and 2020. This system has a huge role in helping us to reach the state championship games in 2018 and 2019, and winning it all in 2019. We are incredibly grateful for the knowledge, expertise, and organization. We cannot thank Coach Maddox and company enough!

I have been using the R4 system since it was released. Dub's teaching has been a major influence in my coaching career. I would highly suggest anyone who wants to improve their overall football knowledge and enhance their concepts and play calling ability to purchase this system. It truly has changed the way I look at the game. The online lessons have been a great tool to further understand the teaching and to reinforce what you have learned.

I am Jack Oholendt, HS Teacher & Football Coach, Omaha NE.. I have been coaching HS Football every year since 1972 as an Assistant coach and most of those years as a Head Coach. My first experience with the R4 Offensive System was when Coach Maddox introduced the R4 System to a room of Offensive Football Coaches. I am a Football Clinic Junkie, what I heard that day was the most Impressive Sequential System of Developing an Offensive Attack and training a QB to a Depth of Decision Making that was way beyond any previous knowledge I had. It was very Logical and Simplistic; it was definitely an Earth Moving moment in my Coaching career. Since that moment until this day, I Study, Read R4 books, Documents and listen to the Clinics and Webinars that Coach Maddow and Coach Ulibarri give as they continue to improve the R4 Offensive system. It is the most complete system of how to train QB & Receiver mechanic’s, how to strategically game plan an Offensive attack on any Defense, how to organize a weekly practice schedule and manage play calling and strategic Run and Pass adjustments throughout a game. If you wish to provide the Highest Level of Coaching football to your athletes and your Community….. Commit and Invest in the R4 Offensive System.

I've been using R4 for over 10 years now. Trying to put into words exactly what R4 has meant to me as a coach is incredibly difficult to do. I cannot imagine coaching without it. Simply put, it's part of my coaching DNA. What I've found particularly remarkable with R4, is how quickly players are able to gain an understanding and R4 becomes the backbone and operating language to our offense each and every year. R4 simply makes coaching easier. From communication to players, communication amongst coaches, installation, gameplanning, to in game adjustments, a better understanding on how to design concepts, a better understanding on how to take advantage of personnel advantages; it's all part of what R4 provides. To any coach who has interest in R4 and bettering their program. I'd highly recommend it.

Trying to explain what the R4 system has done for me in my development as a coach is quite a task. I was fortunately exposed to the R4 system as a high school player and as I got into coaching, the gameplanning and play calling system was being developed. From the very beginning of my career I have looked at football through an R4 lens. This has accelerated my understanding of football tremendously and allows me to confidently organize my offense to fit the needs of the talent we have year in and year out. The benefits of the R4 system are endless. All concepts in football can be organized into certain play families and understanding the relationships amongst these families helps determine what scheme you may need. The accelerator grading process will provide you and your staff with tools to grade the film you are watching and you can confidently gameplan who to attack and how to handle great defensive players. The H.A.L.O. makes it very easy for all coaches to see the field the same way and take away the same information no matter the formation or defense. The R4 grid makes gameplanning your formations and plays very simple by creating a framework that links plays together based on defensive reactions. I have become a much better coach because of R4. It has made the game planning process much easier and effective. I am looking forward to seeing what the R4 staff brings to the table this offseason.

I just finished my 6th year coaching and have been using the R4 system for 5 years . It accelerated my knowledge for the game IMMEDIATELY and still allows me to continue to progress to this day. We see immediate return through the entire staff and players yearly. R4 is a great offensive system that allows our TEAM to communicate and consistently be on the same page. The R4 maps out how to become an elite football program from start to finish . R4 is a GAME CHANGER that immediately excelled our entire programs football IQ. R4 allows me to EFFECTIVELY teach my QBs what is open, provide frames of reference to the entire staff, and puts our team in the best situation each week through the unique game planning process. We live in a world where you must adapt and can never remain the same. The R4 helps our program avoid complacency year after year.

I started as a Wing T QB Coach last year at a high school in NC because that's what the previous OC wanted. The OC leaves and the HC tags me to be the OC, a month prior to the first game. I was reading a book What is Open, by Dub Maddox. I installed an offensive scheme from the book and we went 10-2. As a result two juniors received scholarships and didn't play their senior season because of Covid-19, one committed to Duke the other Univ. Tennessee. A RB/DB a senior, that season, went to Campbell University he averaged almost 10 yards per carry. Our last 5 games prior to the playoffs started with running clocks in the 2nd Quarter. One Team Quit in the 4th Quarter with 4 minutes left in the game with us on the 4 line ready to score.

Ever since I've become a member of the R4 system my football film watching and game planning has been taking to another level!!! This system give your the ability to see the game like never before.

Coach Maddox has done an outstanding job of synthesizing miliatry strategies and football concepts into a clear, concise and comprehensive system. I cannot recommend this system enough!
