It may be a little much, however two quick points:
1- His dad is spending a huge amount of time with his son which is a great thing that many kids would love to be able to do.
2- He clearly enjoys playing basketball. To put in the kind of work it takes to be able to handle the ball like that wouldn't happen if he was being forced to play. He wants to be there and enjoys being good at it. You can tell from the way he plays.
I don't think I love the "creation of a following" orchestrated by his dad and this guy, but there are a lot of worse things this kid could be doing with his time. Being busy keeps kids out of trouble.
