It can go either way. I can scoop the person or the person can break my root. Either way your second statement is probably where the focus should be. "sometime people may put all their attention on their arms and not enough attention on their legs." I would change it to "most of the time." You are also correct that there is a risk of having that leading foot being scooped when it's inside your opponent's leading foot. While it's a risk, it's not a big risk for the reason of your first statement that people don't pay attention to their feet. This also means they won't pay attention to my foot inside of their leading foot. If the opponent is skilled in attacking the root, then the risk almost becomes a guarantee.
When I was a kid, I was told that I should not walk
The danger about sweeps like at that range is that you'll never see it coming if it's done correctly. Your foot position would reduce your ability to see the sweep or scoop coming which is what makes it dangerous. A few months ago I showed a video of someone that I swept using the technique that the OP describes. Even though punches were coming in at me it didn't stop my ability to do the sweep. He never saw it coming.I'm thinking of all the crazy reversals, I can pull, if someone sweeps me from that position, but what if they know some of them? Will I choose the right one?
If you have left leg forward and I have right leg forward (mirror stance), when I move in my right foot on the right of your left foot, you can scoop me and I can't scoop you. Of course I can use my right leading leg to "spring" your left leading leg to your left if I can obtain proper hand control.
It's all about "distance".Depends how hard you hit them
If I'm standing in the range like on the first picture i'll be raining down blows on you non stop, don't think you will feel the need to scoop my foot.
It depends how I ended up there, I suppose. What I picture when I think of being there doesn't look much like the picture (I'm unlikely to be that wide when moving, for starters). If they moved as I did to put me in that position, then I'm probably striking as they are moving, and striking to take structure. If I can disrupt structure, I'm less likely to lose at that point. Otherwise, I probably entered to that spot because of a specific opening that was available, so I'm already taking structure when I get there.
That depends where their weight is at the beginning of the simultaneous movement. The hand has no weight to shift off, but the foot has to shed weight to the other foot before it can move to scoop, or it becomes a sacrifice move.
That sacrifice move is called "shin bite".
I wonder what effect that has if their weight is centered (in the picture, their weight is to the rear). It wouldn't have the same leverage, and would seem to provide opportunity for the opponent to take structure.That sacrifice move is called "shin bite".
If you can use your shin bone to press down the inside of your opponent's leg, you will have advantage.
The "shin bite" is a "door opening move". In CMA, a "door opening move" is a move that you try to use it to set up something else (like boxing jab). When you use "shin bite", you will expect your opponent to fight against you, or pull that leg back. You can then take advantage on his respond whatever that respond may be.
it depends on which side you do it from. It's not a one size fits all. Sometimes one can do that move from the front and other times it needs to be done on the back of the leg. Another option is to apply a similar technique to the inside of the leg. While these are variations of the same concept, the end result will be the same: broken structure.
Someday when one or the other of us makes the short journey, I'll want you to show me some of those. I'm curious how I'd naturally react to them, and whether I'd recognize the pressure early enough to have a response.
