Using Watson, Norman and Langer as examples to the contrary of the Doak argument is a poor effort at contradiction.
Tom is describing training regimens of world-class athletes in other sports. Currently, a guy like Jason Day is my next candidate for Tiger syndrome. These are guys built like Hogan (either in height or frame) who want to be bigger, stronger, faster.
Balance and moderation are the keys. I agree with the Tiger sickness. David Duval tried to ramp up his frail frame, admitted that he fell in love with his look, and injured himself as a consequence.
If the guys were to train like the ladies, they would do just fine. The series that Ron Kaspriske does with Belen Mozo on Golf Digest' web site is outstanding.
If you were to ask any old focker out there what element of his youth he most missed, my suspicion is that equilibrium/balance would be the response.
