These videos are old, at least 2 months, he has been working with them all summer. These drills are some of the basic ones, AB is probably much more advanced by now. I have been following this guy and some of the people who work with him for months now, these are cupcake drills, they have surely put AB through work using more of their advanced stuff but haven't done updates. He works with a lot of players, like Lillard and Paul G. (of course b4 the injury lol).
I know AB works hard, so I have no doubt he is much better than these beginner videos. I'm not saying he will be great, just don't make any judgement based on this early in the process videos.
To the OP, thank you for posting these, a lot of people wouldn't see them otherwise. CB is good for getting the news to everyone w/o them having to look through many different ave.
