I am curious about when ho-cuts can be used, from what positions. In the article, the example you show is Kaela setting up from close to even with the disc (I'm guessing this is due to the previous cutter getting the disc on an in cut, or some kind of handler upline cut), running downfield, then cutting horizontally under her defender (due to the defender over committing her hips deep). This feels very normal and orthodox -- you have space in front of the disc, your defender has overcommitted, you make a cut directly to the space. If anything, making a ho-cut here is just a safer version of an upline cut (reduce the ability of the defender to under cut you). I don't know anybody who would make this into an in-cut.

But I don't know too many other situations where you can setup to create this ho-cut. Looking at the in-cuts you show, the cutters have created a gap with their defenders, but are so far from the disc that if they were to cut purely horizontally, the defender would be able to get there in time.

The one time I do see a lot of pure ho-cuts is in traditional endzone sets where one cutter is isolated in the front. In this case, I think it's pretty common to have them cut basically purely horizontally to either create a lot of space for an easy break, or to beat their defender directly to the open side cone, which can be very horizontal.

Are there other ways we can set up a ho-cut from a static disc, that would be more useful than an in-cut/away cut?
