Tackling Sidesteppers

Question
Ive read your recently answered question about tackling techniques, it was informative but it left out a specific tackling technique that I would very much like to improve upon. I am about 5"9, 17 years of age and a wing for my local team.I have no problem with tackling bigger players than run into me rather than around me, but i have real trouble with attempting to tackle other players around my size/weight, who tend to side step a lot to get around me. I was wondering if it would be possible for you to give me some pointers on how to tackle the more agile player, the 'nippier' smaller players? That'd be great, thanks a lot.

Hi Lee, I have just come on the "experts" and Allexperts.com. I see your question about tackling "nippy" players.

If you are still looking for advice: I suggest the simplest thing. When a nimble player is moving towards you do not look at their body as a whole, instead focus on the point of center between their hips. Often a coach will tell you to "eyeball" the "string of their shorts". This focus will allow your brain to only register the runner's center of gravity: the "mass" of their torso. No matter what a runner's arms, legs or head does the torso is usually stagnant.

Keep you feet active, stay on your toes either moving towards them or running in place. Close the space between you and the runner swiftly but stay in control. This is to limit the runner's options as much as possible.

Focus on the "string of their pants" and drop your center of gravity to set up the hit. Aim the shoulder to that string.

so summarize:

1. keep the feet active "live"
2. focus on the "string of their pants"
3. drive the shoulder to the "string of their pants"

Let me know how it goes.
