Learn More About the 4-3 Defense System 

The One-Stop Online Resource to Teach, Install, Execute, and Win for any Football Team.

Coach David Carter has a proven track record of taking defenses into the championship level.

"As a competitor, there is one game we play that I look forward too above others, and that is St. George under Coach Carter. There is a joy in having to prepare for so many coverage change ups, blitz adjustments, and Dline games that Coach Carter will bring. We are an offense that does what we do regardless of our opponent, but playing Coach Carter ALWAYS requires us to think critically about every play in the plan that week. In my 3 years at Harding we have averaged 39 points per game. In 4 games against Coach Carter we are averaging 19. This scheme is one of the toughest I've seen in high school football."

"Dave Carter is an excellent football coach with collegiate coaching experience and a passion for the defensive side of the ball. He possesses a very analytical and creative mind that allows him to effectively game plan to maximize the strengths of his players and neutralize the strengths of his counterpart." 

Tom Allen - LB’s/Special Teams - University of Mississippi 


"Coach Carter and his staff do a great job of coaching the multiple 4-3 defense.  His defenses are versatile, fast and physical. The defensive schemes are difficult to prepare for and challenging to play against. I highly recommend Coach Carter's defensive scheme to anyone interested in playing at a championship level." 
Mickey Marley - Head Football Coach University School of Jackson
