Y is Not the Letter of the Day

In a world where you have access to piles of instructional tips, articles, and videos, where do you turn? How do you know what's right?
The more I look at the "information" that is out there, it becomes more and more apparent that I need to share quality information for the world and start debunking the myths that are out there.
I recently ran across a post that outlined a supposed "checklist of things that everyone needed to do in their putting. I sighed and finally decided it was time to do something about this.

Stop the Madness!
I figured why not start with this common misnomer that creating a capital "Y-shape" with your entire arms and the putter is part of an effective setup. (Pun intended)
At first glance, this seems like a pretty good idea. It's a stable appearing structure and should be easy to replicate. But, as with most things in golf, it's never that simple.
When you take a closer look at the structure of the arms, you'll notice that there's more than just the three pieces of the capital Y providing some good putters the structure you see at their setup position.
