julray, I know the question was asked of Five, but if I might....the video in question is when Bobby was just starting to get the idea of "barrel to the ball", "TTB", and "Shift AND Swing" vs "Shift THEN Swing" down as many of us had/were experimenting with back then...and he was also just starting to get out in front of the camera, and trying to figure out the best way(s) of trying to get his point(s) across early in his coaching career.
With all of this, and all of us...over time things change, and the more we all worked with the concepts, the more comfortable we became with them, and also started incorporating our own teaching styles and terms into them, and why in the later Tewks video you just posted (2013) Bobby has a more in depth understanding of the various swing types...having worked with a lot more hitters than he had prior to the filming of the first clip that was posted (2010)...some of whom were now playing at the highest level of the game, and credited Bobby for a lot of their success in getting there (Colabello).
As far a Antonelli, while I really like his presentations on the material...he like so many others (Justin Stone is another) were late to the party, and have benefitted from all of the "early party-goers" who literally battled in the trenches of the these forums in taking something that was bitterly disputed to something that many are now seeing, and using...even if they try to argue that they are not, but have rather created something "new" that's earthshaking or revolutionary. There's nothing wrong with that btw, as even much of what many of us battled about (and still do to a much lesser extent) can also be attributed to some of the things old Ted William's was trying give us way back in the day with his book "The Science of Hitting".
So hopefully this gives you a little background into why it may appear that what Tewks said/showed in the first video might not be the same as he, and others are talking about now in later videos out there. But it's also the reason his first clip was 2 minutes and 17 seconds long, and his subsequent ones are 20-30 minutes long once he gained a much deeper understanding of the material, and had much more experience in the presentation process in order to be able teach it at the highest levels.
There's plenty of good instructors out there (and plenty of not-so-good ones as well)...the big difference in the good ones, is how long have they been teaching what they're teaching, and how well do they really understand the material...versus just parroting something someone else had shown or told them at one time or another. Perfect example: the "one-legged" swing. To this day we still have some very old forumers who believe that "one-legged" literally means that some believe the swing takes place only on or with "one-leg", which is so far from the truth it's laughable, but yet they still try to pretend that that's the belief of some, and still poo-poo it today because they never took it upon themselves to understand it in its proper context or learn how it's used to actually help many a hitter. Just saying....
Best of luck, hope that helps clear somethings up a bit,
