A jump from kicking distance to someone's chest isn't small. And if they are already grabbing at your leg, then grabbing at your leg is pretty much the same thing.and the jump is in response to some one trying to kick or leg sweep me, they cant leg sweep me and grab my leg with their hand at the same time, even then you are not pulling some one over at two foot distance, you would need to wrap your arm around the leg, just grabbing an ankle is not enough purchase
