Pulling Through With Left Arm

[parryben]

I HAVE A FRIEND WHO IS AN ASSISTANT PRO AT A LOCAL GOLF CLUB. HE HAS TOLD ME THAT I AM ROLLING MY WRISTS ON THE BACKSWING AND THIS IS REASON I AM PUSHING OR SLICING SOME/MOST OF MY SHOTS. IS THIS CORRECT AND DO YOU THINK THAT PULLING THROUGH WITH THE LEFT ARM (SEEN AS THIS IS THE STRONGER ARM FOR A RIGHT HANDED PLAYER) ON THE DOWNSWING COULD IMPROVE MY ACCURACY. I HAVE TRIED IT AND IT SEEMS TO HELP BUT WHAT DO YOU THINK. AND COULD YOU PLEASE EXPLAIN TO RIGHT HAND DRILL OF GREG WILLIS BECAUSE I AM LOST WITH IT. I NEITHER UNDERSTAND IT KNOW DO I KNOW HOW TO APPLY IT.

THANKS
