How do you apply the Jack Dempsey drop/trigger step to the right cross/left hook?

[OMGWTF]

The drop/trigger is also often referred to as the falling step...See what I mean? Your weight is basically 'falling' forward, not twisting or rotating. You can't 'fall' forward and throw a left hook, as the weight needs to get going in a different direction. You can 'step' in and hook, but bring your right foot up, maybe slide it to the right a wee bit, so the weight has a place to go.

Ok thankyou so for the left hook I would have to fall to my right.

What about the falling step for the straight right? I cant rotate my hips very well or get the normal hip weight transfer AS I do the falling step fowards. Hows it done?

I read one description that had it this way: Put all your weight on the left foot, lean so far up on the left foot that you are about to fall over. Then take a giant step forward with the left foot. I suspect that that was meant as an exaggeration to get the feel of the move and then to be refined later.
Try this instead...You know how, when you are doing footwork drills, you move in small steps? Start moving in big gliding motions, like a fencer. You're pushing off of that rear foot. Get in the habit of moving your hands and feet together- so when you push off and the left foot moves, move the left hand with it, drive the arm straight out. When you bring up the right foot, you are throwing the straight right, driving it all the way out. All your weight is coming forward; do it a few times and you'll start getting a feel for how you have to get your weight over your left leg. I could show you in a minute or two but I don't think I could possibly explain it typing.
The things about doing it that way, is that it is a very graceful move and maintains balance. And you can instantly slide back out of range...in fact, try it going forward and then backward to get the feel and your balance before you try it with the punches.

I dont see how this helps, it just makes everything more subtle, its great for normal footwork it keeps your weight nice and even and its fast, but it makes the drop step more subtle and therefore less powerful and it makes my weight transfer problem less of a problem but its still the same problem just a more subtle version, instead of all my weight on my front foot, now most of it is but not all of it, so im no further foward its still the same problem. That dosnt help at all.
