The point is that the attackers forced the opponent to move and then capitalized on exposed weaknesses. Basically what the successful attackers did was utilize the rule of inertia. The rule of inertia applies to Judo skills the same as it applies to anything else. There's a very simple lesson here. In newaza, or tachiwaza, your opponent has to be moving in order to be able to execute your skills.
Many Coaches already use the principle of moving the opponent to begin a newaza attack.
It was very surprising to find that less than one percent of the newaza exchanges resulted in scores. It is, undoubtedly, true that players are getting better at defending themselves. It is also true that many players know better than to waste precious match time trying to assault a strong defensive position. However, I believe that the root cause of the lack of scores is the simple fact the majority of the players simply don't know how to deal with the situation. This research has suggested a need for change in Coaching behaviors and practices.
