I noticed that on the DVD and have kept my mouth shut because I really couldn't believe that Jerry really thought that. Well, Jerry, and Bob, I have to disagree with you strongly.
I decided to go downstairs and do a test before I posted anything. Here's what I did- I put an ob on the center spot of my 7' table. (I have the center marked) I then froze another ob behind it aimed directly at the center pocket. Put the cb about a foot behind the two ob's. Hit 1/4 to the left of the back ob. That ob will go 3/4 diamonds farther up table than with no draw on the cb. In fact, it missed going in the side by about one ball width.
Next, same set up, except the cb is in line with the two frozen ob's. Using heavy draw, the back ob picked up enough forward spin to go to the end rail and back one diamond.
Knowing that the frozen ball can be alter dramatically from it's tangent line is a huge factor when playing frozen balls.
However, I DO agree that putting follow on the cb will result in very little difference on the ob. You can change it to come back from the tangent line a little, but not much. SO.... you can put a lot of follow on the ob using draw on the cb, but very little draw on the ob using follow on the cb.
