Making tackles in football is not only challenging, but it can also be very dangerous. It is important that players know exactly what they're doing when making tackles in order to prevent injury to oneself and the opposing player. During the game of football, very rarely are players standing still. That's where the importance of angle tackling comes in. In order for a defender to stop a moving ball carrier, he must ensure that he is coming at the right angle and using the proper tackling techniques.
There are several steps a defender must take to ensure he performs a successful angle tackle. He must remember to keep his body low to the ground because you'll never be able to make a tackle standing straight up. Once the player is low, he must wrap up the ball carrier with his helmet across the offensive player's chest. If your head is behind the runner, you could risk serious neck or head injury. The wrap-up should take place at the ball carrier's waist. Once your opponent is wrapped up, it is important to lift them as much as you can and chop your feet. When the defender feels they have enough leverage, they can finish the play and bring the runner to the ground.
There are several drills designed to specifically work on this technique, but they all have the same concept. These drills can be done at walking speed, thump speed (wrap-up but no tackle), and full speed. In order to set it up, you need two parallel lines: one for defenders and one for ball carriers. Have a cone set up 5-10 yards down field, in the middle of the two lines, to be used as a meeting point where the tackle is to be made. When the whistle is blown, have the defenders tackle the offensive player at an angle, making sure that the player is using proper techniques. It is always important to know how to tackle safely. Drills like these are still practiced at the highest of levels.
