Watch a tournament and see how often you see this:
A player throws and there is a second or two from the throw until following up to the mat. In that second, the opponent turns on his or her stomach, rolls to the side or sits up. All of these split-second moves put the opponent now into a little better position. Why didn’t the player who threw IMMEDIATELY follow up to the ground?
Look at the players below. They are in a beginning class and just learning to do throws and hold- downs.
They are practicing a drill where one person throws and then goes into a pin the second they hit the mat. The student has just thrown and he already has the opponent's right arm locked under his left arm for the pin. He didn't need to move his right arm because it was in the right position for the pin when he came into the throw. Unfortunately, this is NOT the way most people learn matwork from the very beginning, which is why they make mistakes later on.
