I worked with Grady daily for an entire week in 1995,and later on for 2 weeks. At the time,my high run was 63.
During a practice session,I was already on a run of 42 and was getting ready to shoot a wide open ball,when Grady asked me if I wanted to continue the run,and I said "of course".
He stopped me and told me to look around at the other side of the stack. There was a makeable shot,but a little tougher than the ball I was about to shoot. He pointed out that this might be a tougher shot,BUT this shot was a much better secondary break. I took it,made it,and the rest of the stack scattered. I finish the rack,so I'm on 56.
In the next rack,I was jellied up on top of a ball underneath the stack,and was about to play safe,when he spoke up again. This time,I almost ignored a dead ball in the stack. I make it,and keep going to 70.
This kept going until I was at 114,which I have only come close to once since. It didn't really matter,because he turned around and ran 200 on me

.
What it taught me most was that sometimes,it pays to put your rhythm on pause and look around at the table 3-4 different ways,because you might have missed something.
He said overall,that my shot selection was pretty solid,but added that my stroke and execution was what bailed me out several times during that run.
I'll treasure that night for the rest of my life. Tommy D.
