According to Timothy Gay, a physics professor at the University of Nebraska and author of The Physics of Football, a DB's mass paired with his speed—on average, 4.56 seconds for the 40-yard dash—can create up to 1600 pounds of tackle force. More commonly known as "tackling," this type of force is what causes injuries to players. A tackler can apply up to two tackles per play; if he or she does not wrap up a ball carrier immediately, another player can be assigned the task.
For comparison, the average weight of an NFL quarterback is 220 pounds, and the average weight of an NFL running back is 230 pounds. Thus, a linebacker or defensive back who carries his weight well can put out more than 100 pounds of force when making a tackle.
When a player engages in a tackle, he will use either his arms or his body to apply a restraining action on the opponent. Based on how the player uses his body, there are two types of tackles: a clean tackle and a dirty tackle. In a clean tackle, the player uses his arms and shoulders to apply pressure against the body of the ball carrier. This type of tackle is most common when the player is making the tackle after a breakaway. In a dirty tackle, the player uses his body to shield the ball carrier from opposing players. He accomplishes this by wrapping his arms around the ball carrier or pushing him off balance.
Body weight has virtually little to do with tackling. You'll be tackling harder in no time if you use your speed effectively, master your body posture, and explode into your opponent appropriately. Put your feet in the proper position. Point them forward (not outward) at a 90-degree angle to the line of movement. Make sure one foot is positioned slightly ahead of the other. This will give you better balance and stability when hitting someone.
Now that you're balanced and ready to go, bring your knees up under your shoulders and down over your hips. Bend your elbows and swing them back as you drive them forward into your opponent's chest or face. Be careful not to let your arms swing too far backward or they may cause you to lose your balance. Also make sure not to cross your legs; this could be a disadvantage because it would prevent you from getting off the floor quickly if you need to.
Finally, hit hard and fast; don't hesitate because then you won't be able to stop yourself before you connect with your opponent's body.
That's all there is to it! These five tips will help you get stronger, faster, and more effective when tackling. Good luck out there players!
When attempting to tackle more difficult tasks, it all boils down to basics. Your feet should be shoulder-width apart and directly beneath your hips. If your toes point forward, that's called "toeing" the line and it's unacceptable. The goal is to get both of your shoulders under the arc of the ball.
Now put your hands on your hips. Don't hold them out in front of you because that's a sign of weakness. Keep your arms by your side but ready to strike. That's how you should stand for the start of every play.
Finally, charge! Run full speed toward the opposing player and hit him or her as hard as you can with your shoulder or helmet. You should aim to bring your opponent down to the ground using only your body. Once you make the tackle, don't let go right away! Stay on top of your player to prevent him from getting up again.
In conclusion, there are two ways to improve at tackling: practice making them and practice talking yourself out of trying. No matter what kind of player you are, everyone can benefit from practicing their tackles. You won't be able to improve without any contact though, so have fun but be safe!
