I don't like the swing in some of the videos because I think he doesn't load properly (almost tries to be too quick) and he drifts too much. The tools for timing just seem off, and it doesn't look like a real pro power swing. Something is off with his front leg and how he uses it / plants. I think he's also trying to be straight to the ball, which is lame.
It can all be fixed.
Being said, I watched other videos and his swing is, unsurprisingly, different in some of them. He's a kid so maybe his swing is "sweet" and it's just the one look that I don't like and/or I have no idea what I'm talking about.
For the record I have no idea what I'm talking about but I do have a really high IQ.
