Birly,
We don't yet know what Jeffy is proposing as an alternative so it is hard to know whether it is a big deal or not.
Seriously? You haven't been paying attention. The following from Jwat's thread is representative, plus, of course, my comments on Brian's video posted earlier.
I feel like I never turn my right rib cage or right shoulder around enough on my BS. Alot of the time I actually catch my right shoulder shrugging on the BS which totally stops my turn. But when I try and turn my right hip more around it seems like I reverse pivot even more.
What do you think the solution is to getting my right elbow out of my right side?
I like Brian's "four point program" for you. I'll add a couple comments of my own.
1. Find a way to turn your back to the target. Anyway you need to.
Obviously you need to work on this. It could be mental as much as physical. The age-old advice from "Five Lessons" of "pinched in right knee" and "restricted hips" has created generations of golfers that are afraid to let the right knee move away from the target (rotate externally) which all but the VERY most flexible need to do. Look at Kuchar's right knee:
I try to do the same thing and even turn the right foot out to facilitate the turn (I'm 56, btw):
Hell, Snead was as flexible as anybody and he did it, so you shouldn't be afraid to. You also might start with a little move into the back leg at the start of the backswing, kind of a back leg loading motion.
Something difficult for many is the concept of "internal rotation" of the right hip. This is basically the right hip rotating clockwise around the right femur. You don't let that happen. But, when you do that, the femoral head (the knob at the end of the femur) will shift backwards towards the target, what you may be feeling when you say "when I try and turn my right hip more around it seems like I reverse pivot even more". That's why a little move off the ball won't hurt you IF you allow the right hip go into internal rotation.
2. Keep your back turned to the target as long as long practically can, while your weight falls back toward the target.
A good thought here to try is to HOLD the right knee in place for a split second and start the downswing with just the left knee moving into the bow-legged position. Nicklaus is a great model:
The long drive guys exaggerate this, as we can see with Sadlowski:
3. Be as bent over your waist as you ever are in the swing when you add some ummph to the club between when your left arm is level and the club is parallel for the last time pre-impact.
This is pretty important: getting bent over at the waist with the knees flexed. You're an athlete, so I'll let you figure out how best to do it!
4. Recruit every fiber of your body to completely lose all of the forward bend you had, as you unwind some, and shift your center of gravity forward, assisting your arms to pull the club inward.
What Brian is saying in the first part is to use your posterior chain (the continuum of muscle and fascia that runs from the base of the neck to the ankles) to extend out of the bend or "jump" through impact. At the same time the legs should snap together. Again, Jamie does this to an extreme:
Squats, dead lifts, thrusters, box jumps, rowing, lunges all use the posterior chain: it is where the most power in the body comes from. So use it!
