There are many styles in wrestling - however, in high school wrestling, for the most part, if you are going to win the State, you will have to leg attack, and counter leg attacks.
In order to leg attack, you have to move your opponent, and you do that with your hands and with your feet. Handfighting allows you to move a head, arms, or get a reaction by tapping knees. You move your opponent's feet by circling and getting motion with your own feet. The combination of the two is essential in order to effectively and consistently set up your opponent for leg attacks.
Whenever you handfight - whether it is clearing the opponent's hand off your head, or using an elbow pass or other techniques, always move your feet, level change and have your attack leg forward. Always train to attack off handfighting techniques - in other words, position yourself to attack - and you will be much better positioned to hit your shots.
