Nope.
"Straight from the horse's mouth" suggests that linking to this article was a new piece of information pertaining to an existing debate. Even if you failed intro English at Lehigh Valley community college (quite possible) you can probably admit to that.
Here's an analogy. (That's when you compare something to something else):
I wouldn't link to an article on breast size reduction by Phil Mickelson's personal cosmetic surgeon, as useful as that article might be for some on this site, and frame it by saying "straight from the horse's mouth." That would make no sense. There's no existing debate. No context.
Boob.
Now all I have to do is figure out how to fit all the words in that entire master class of a burn into an enormous six paragraph essay.
