Drastically. For one thing, pinning your opponent's shoulder to the mat is no longer possible. Very different criteria would be required to determine winning. The different objectives would in turn make the sport very different. The reason pinning against the mat is no longer possible is because there is no sustained force possible against a flat surface. Any push against the surface will accelerate you away from the surface.
