No spin here

It is very easy to see that Bertholy did not influence Moe's playing career. There is no spin involved. Moe started working with Bertholy in 1978. Prior to then Moe did all of this:

1955 Canadian Amateur Champion
1956 Canadian Amateur Champion
1957 Runner-Up Low Canadian Open
1958 Canadian Open
1958 Ontario Open Champion
1963 Saskatchewan Open Champion
1963 Ontario Open Champion
1964 CPGA Miller Trophy Champion
1965 Manitoba Open Champion
1965 Runner-UP Canadian Professional Golfers Championship
1966 Canadian Professional Golfers Champion
1966 Alberta Open
1966 Manitoba Open Champion
1966 Quebec Open Champion
1967 Manitoba Open Champion
1968 Saskatchewan Open Champion
1971 Alberta Open Champion
1971 World Cup National Team
1974 Canadian Professional Golfers Champion
1976 Alberta Open Champion

What do you find difficult to understand here? It doesn't seem difficult to understand to me.

I do think that Bertholy was a very good teacher, but it very easy to see that Moe did not learn his swing that he used in the above tournaments from Bertholy. If you have proof otherwise then please post it.
