The line is out in wrestling, just like football. If both wrestlers are out, it has to be stopped. Some officials do stop the match in some cases to prevent/avoid any controversy with an edge of the mat call if there's nothing significant going and to keep the action going..sitting near the edge isn't too exciting. That's good officiating in my opinion...

And to our Colorado friends, please forgive our manners, we sometimes forget them. I am certain both these teams are very talented, respected, and well-coached or no one would be writing about them.
