Well, you'd need low launch (low Vertical Face, negative Vertical Path) and low spin (face and path cannot differentiate too much).
So, even though it would seem like a relatively shallow AoA with lots of forward lean to keep that Dynamic Loft low would be the "ideal" we generally see guys achieve a decent compromise with a little more downward Vertical Path (than the "ideal") and not quite as much forward lean, allowing for a controlled Vertical Launch, even with more spin than the "ideal."
Although, wasn't Watson a "picker?" So, maybe his success was partially related to that?
Just thinking out loud...
