To me out of bounds is a mess. It is crazy for a ref to have to try and look for a fall/back, and see if defensive wrestler is in, and see if offensive wrestler is in, and see if the offensive wrestler is in AND if a knee comes up. CRAZY! I think a ref should have two things to watch: 1. is anything in bounds-wrestle. 2. If danger-blow the whistle (danger means whether both wrestlers are in bounds or not, like if a mat is too close to a table, stop, too close to other wrestlers, stop, if on floor, stop). Really seems simple to me. As a coach, there is no way I could argue a takedown was there if they are on the floor, or close to table, etc.(danger).
It’s like driving a car: If I approach an intersection with a green light, but I see a car/human/dog I am going to stop. As long as ref’s don’t start texting and reffing, we should be good to go.
I don’t really like the “cylinder” either. Another thing to imagine/think about. If something is inbounds on the mat, its in. If everything is off the mat BEYOND reaction time (so like a hop for adjustment, or step, etc. let it continue) then it is out. So if it floats, its out.
On the line, wrestle. Danger, stop.
