I watched a dual last Thursday and time and time again I kept saying to myself " fish ". I personally think of a fish when a kid doesn't grasp angles. For example when a kid is trying to hit a gramby and the other kid blocks it with his hips but the kid doesn't feel his weight counter and keeps trying to roll through and gets pinned. That is my classic example of a fish. And it doesn't always mean lack of experience. One of my good wrestling buddies who was a state champ for south and great overall athlete didn't see his angle on a match and pinned himself at a kids regional. That was a fish move (and pretty **** funny), having a brain fart during a match doesn't mean you lost your heart but can make you look like a fish.
Those are just my thoughts on the subject.
