Mechanics are very important when pitching, being a 2007 draftee I talked to a few people and they could careless about what your balance point looks. They look at the fluidity of your arm and your body as you are going through your mechanics, how the ball comes out of your hand, can you constantly repeat your mechanics. These things are key factors in consistently throwing strikes. I think your right on the money, and this kid needs to work on mechanics and not so much how he looks.
Francisco Rodriguez looks weird throwing, but he repeats it every time. Same thing with how Hideo Nomo used to pitch. Its all about repetition.!
