This is from my personal experience, but what I have seen is most people's problem is their post game. Either they do not know how to properly execute post moves and just back down or they don't know how to cover a player like McHale when he's in the post (Let's be honest, there is nobody better down in the post

)
Can't wait for the next video's, let it be more educational so people with no prior experience in basketball can understand how beneficial some moves are like the Give & Go, Rolling Inbound pass and anything else you may find. I am here if you need help
