I'd like some feedback on Daniel's delivery. He needs to simplify his motion, and I think he rocks back too much on the way to the plate.
Looks like he does a lot of things well. Personally I would do away with the counter rotation, just misdirected momentum. Try to get momentum towards the plate as he begins his leg lift.
I think it looks pretty good. I would have him use his front leg more as a brace than landing right on top of it. This should help him rotate around his front leg more than being squared up to the plate after release.
