Please consider this as part vent and part observation. Something that has amazed me in my time in coaching both on sites like this but, more importantly to me, on teams I coach is the inability of parents/dads mostly to admit that their guru's stuff simply is not working for their child and therefore just might not be the answer. How long does it take for parents to understand this? For example, I can cite one example of a player going 0-28 and yet, the parent remained loyal to their guru and promoted said guru for others. I just shake my head at that. On these various sites, I can recall poster's who's dds or sons (I moderate a couple of baseball websites.) and they remained loyal for a very long time. These same parents then try to get others to seek out the guru. Naturally, there were the cases in the "hitting wars" where it got real nasty as some parents figured stuff out and others refused to see what was going on. (That would be on both sides.)
As I've thought about this, the one common denominator is that the guru always promotes their stuff as the MLB Swing or the High Level Swing and assure all that will listen that they have unlocked the answer. This is followed by the mention of several MLB players or high level softball players, video of same and then some statement that the guru teaches this swing. The parent most often doesn't have the information early on to dispute these points. Still, when you see swings that are so far removed from what was shown in the video or you have swings that lack "adjustibility" and so lead to high strikeout rates, I would think that the parents would figure this out and move on. One that eats me in particular is a "guru" who teaches what I would call a 2 part swing where the hitter starts the load/unload, stops momentum after getting that foot down early and then finishes the swing having killed the running start.
As a hitting coach, I do my best to teach the same things I taught my dd. I do my best to keep up with the changes going on. I know the history of most of the changes and the changes that aren't really new but just different takes on old but good stuff. Sometimes it is hard for me to let some stuff go and just move on. Thanks for letting me vent.
