You basically see the people all the time on public courts. Jake McClain was a perfect example.
If they play this way for long time they actually can get very consistent. Problem is that if they keep hitting the same way they can practice 10,000 hours and still be 3.5.
There is some truth to this but I don't think anyone said no instruction, certainly in every sport there is need for some instruction. Most of the players I know that get injured are experienced players with good technique but have gotten older and are not as physically sound as they should be.
Most instructors would say that rafas forehand is incorrect or roddicks serve, same with johnny macs serve. These guys made a lot of money with some unorthodox tennis techniques.
