Working on your timing and footwork might be a good idea. You seem to have a lot of extra energy at the line and it's causing you to post up. It also could be a result of like the others said not having a straight or straighter swing, or both. I stuggled with the same sort of thing a little while ago and now that I fixed it up or I'm at least aware and trying it has made a big difference.
Nice reaction out of the ball though. I tried to throw the ball like that. I couldn't get it to work for me. Glad you were able to get it down.
