Never said Hanson was fine. Just said I wasn't able to find any obvious timing issues, and cautioned that weird looking mechanics don't always mean bad mechanics. Sometimes guys can do weird looking things and still hit the important parts. Lincecum is a great example of that. Now the negative to Lincecum is because of how athletic his mechanics are, as he aged he is not able to complete them with the same consistency as he used to. Which is why I believe his BB rate started rising pretty fast, not able to consistently repeat his mechanics and I think long term it will lead to health issues.
Beachy didn't have an inverted W, that was Medlen. Beachy had some of the worst hip/shoulder separation. I never even made it up to analyze if he had an inverted W or not. Hip/shoulder is enough of a killer as it is.
And if you don't know why it's called the Inverted W you've never asked or never read up on it. Here's the answer

so basically it was originally called that and out of deference to the person who popularized it (even if he didn't figure it out) peopel stuck with it. It will be called an M at some point I believe. Probably when people get tired of saying or typing inverted W over and over again.
