I think I've finally figured out the basis for these "HS v TB" argument...
It is called 'self-selection bias'. (E.g., conducting a poll at the RNC and ask people if they think Reagan was a great president.)
The parents on this site generally understand the game and want to learn--otherwise they wouldn't be here. So, these parents find a good TB coach for their child. Often, they find great TB coaches. Their TB team almost always has a high winning percentage. When they go to a tournament, they see their coach...and then they are always playing late into the tournament against other good teams with good coaches. The bad coaches are usually long gone by Sunday.
But, when these parents get to HS, they have had no control in picking out the coach. So, then they are the mercy of the percentages--and they discover that their HS coach usually isn't as good as their TB. Why? Because the parents have a good TB coach, or else the parents wouldn't have paced their child on that TB team.
Thus, you have "self selection" bias--the parents on this site pick good TB coaches and find, not suprisingly, that the HS coach isn't as good as the TB coach.
If after you child gets out of TB , go watch a tourney. You will find scores of very bad coaches. The usual bad TB coach is the guy/gal who has no clue what is really going on, but pretends. (E.g., I saw one guy doing the "bare handed fielding drill", which is a good drill, but in his case he had the kids back at 60 feet and he was hitting liners to them.)
I have seen really good HS coaches. In HS, my kids played for probably a dozen different coaches. Of those dozen, there was one excellent coach, three good coaches, and the rest were mediocre to poor. (I'm not evaluating based on 'winning' and 'losing'--I'm evaluating what they did with the available talent.)
Good point slugggers your probably correct but that doesn't mean I have to sit back and watch my kid go backwards for 3 months and not get off the bench just to please this coach ....I would much rather work with her myself and with her hitting and pitching coaches and skip school ball all together.....
