You make some good points. From an instruction perspective I kind of figured the ones that have had greater influence on amateurs have gained some well earned notoriety. But then I thought that there are so many people “in the masses” that it turns into a drop in the bucket for influencing pool overall. I thought I’d turn my head toward who might have had the most influence in elevating the games of professional players.OK, fill me in. Who, other than Fedor Gorst, has he groomed to become a world champion? Johan is also the mentor of Ruslan Chinakhov, a super straight shooter but probably never a world's top 25 professional in anything but straight pool. I also know that Johan did some great work with Skyler Woodward, helping Skyler get to the next level as a competitor, and that he did the same for Tyler Styer. Obviously, Johan is an amazing instructor, a legend in his field, but he hasn't, to my knowledge, groomed that many players that went on to become top professionals.
Johan may not even be among the ten most influential instructors of this era. Jerry Briesath has probably worked with twenty times as many players that went on to be top professionals over the years as Johan, but I wouldn't put Jerry in the category of most influential in pool either, despite the fact that he has served the game so very well over the years. I think the instructors that have been the most influential in pool are those that have mass taught the amateurs, especially those that have run the national organizations set up to teach the amateurs while also setting the national teaching curriculum. In America, that probably means Randy Goettlicher. I don't know who it would be in Europe or Asia.
I know he’s credited for his work with Niels Feijen and Alex Lely. I assume he’s played a core role with Fedor, Ruslan and Kristina. I assumed there were other top level groups he’s worked with but maybe not. And I don’t want to emphasize the outcomes of being on the winning side of Mosconi Cups because I don’t think that is influence, but I can’t help but assume his approach to coaching might have similarly elevated the players he did coach. Could perhaps Appleton, Shaw, Melling, Boyes, van den Berg, and maybe Filler become stronger players due to time with Ruijsink. Like you said, Sky and Tyler certainly improved under his guidance.
I’m probably giving him too much credit but I can’t help but wonder if he’s contributed a greater emphasis on routines, drills, regimens, and discipline to the training practices of professional players as opposed to the old “gamble until you’re good. I don’t practice” mentality. Every time I see Shaw do a crazy drill on FaceBook wonder how much Ruijsink influence is behind why I’m watching that today.
I think Briesath could fit in that category for who he’s worked with at a professional level but I was thinking more in terms of current influence which I assumed his contributions were starting to shift from current to historical. But that could be a naive statement.
