i like the 4 point near fall, also like college out of bounds. The changes would make things more interesting.
Another benefit, in my opinion, would be that a casual fan could watch a college match and a high school match and not be confused about the differences. The NCAA's had crazy amount of people watching and we are all trying to grow our sport. The fans would understand more, and our kids that want to wrestle at the collegiate level would be prepared for it better.
