This discussion board provides some great information and alternative insight into the game of golf. Not meaning to offend, but in reality Bertholy is not known as a great instructor to the majority of golfers or high level pro golfer or instructors. He is only known to a small fringe group of mediocre passionate recreational golfers and instructors as one of the greatest teachers ever. He is rarely mentioned in the same class as a Pennick ,Flick, Peltz, Haney, or Harmon. I admire Moe Norman for his accurate, repetitive swing, but Moe was promoted as a great golfer by a fringe group of people who wished to make money by using the notion that his swing was simpler to learn. The mainstream and majority rarely refered to him then or now as great. He did have great dedication to the game but the sad direction life took him to and his off beat behavior was a big part of his notoriety not his golfing successes which were few and for a small period in time. His pro career and his overall golf records do not put him in the same class as a Hogan,Nelson,Palmer,Nicolas Woods and a hundreds of others who have played golf. Greatness in golf and sports is reserved for players that performed and succeded at the highest level of competition. Greatness in sports and golf as a teacher,instructor or coach is judged by the success of your students and players at high levels of competition. I know Trevino and Singh have acknowledged and admired Moe's sweet swing, but just as in basketball many fringe players have gained noteriety because they have won the three point shooting contest and slam dunk contests at all star weekend. They are not considered great because they do not perform when it counts, in a real game competetition and for a significant period of time.
