I said you cannot cue a ball, not you cannot pot one. Whilst all great players, many of those you list have appalling technique, and play well in spite of it, not because of it.
Someone mentioned the england football team earlier, and he gets no argument from me there are systemic problems with our technique, and has been for decades. The trouble is, your average British football fan/player/punter doesn't see the problem, so it persists.
The problem you have is cultural, just as ours is with football. If you don't change your culture you're finished as a pool playing nation. And saying this only gives me a modicum of pleasure - it is in all of our best interests to have a strong pool scene in the US.
It really is up to you. If you are happy with the state of pool in America, good luck to you - you're going to need it.
Since when did standing square to the table with an open bridge and taking 20 minutes on your pre shot routine become the proper technique to "cueing" a ball?
Keith McCready would walk all over your proper technique with a grin on his face.
