Hi Phil,
I'm sensible enough to know that you could come up with a few names of people who have coached
some of those I named, at some point of their lives, for some weeks. But you cannot get away from the FACT that for every Wilson or RF there are a dozen who did make it to the top without mind management coaching or tecchy teachings for that matter. Winners have a lot of things they're born with and conquering their mental devils is one of them, RF would have got there regardless, it was just handy his parents could afford early tuition.
Who taught the early Olympic winners of the past, and not just in shooting?
