Ive watched some of these top flight travel ball teams and I have to say that they are not very fundamentally sound at all (not all their are exceptions) they just have top flight pitching so their fundamentals are hidden more than the lesser travel ball teams with average pitching at best so the ball is put in play more often. I've watched top tier teams and watch their players and wonder how some of these kids are going to top flight D1 schools with the tools they have just my .02
They pay top dollar to a big org. and get promoted like crazy, that's how.
People seem to think getting a top D1 scholarship is the end of the road. It is really just the beginning for the college level.
Look at how big the classes are for some of the big D1's. They are huge. There is no way all of these players will make the cut. For almost half it will be one and done. Keep track of who is on rosters their freshman year, and just disappear the next. I do. So marginal players who are promoted like crazy sometimes are buying a pig in a poke. One year in college and out, because they are not good enough.
By the same token, every College World Series has a few players in the starting line-up who started playing D2. The announcers always want to say "gee, here is a player the scouts missed coming out of high school". Yeah the "D2" did not have much money. Was not promoted, or had attitude problems, possibly in her teenage years. But here she is, in the college world series batting 5th in the semi's.
