As grandma used to say, this (unfortunately) means somebody's momma didn't raise them right. I have seen too many excellent wrestlers succeed with great character to tolerate that type of behavior.
For a kid to tell me that fishhooks was an accident (especially if it wasn't the first time) is a kid telling me that he thinks I am an idiot and will hide behind the "well your MY guy and I gotta believe you? DUH!" Kids need boundaries and to play stupid tells them that it's OK, the end justifies the means.
When my son was young(er) he came off the field in a youth football game and threw his helmet. As I drug him to the car, he tried to tell me he "dropped" it. He was BS'ing, we both new it and as painful as it was for both of us I could not tolerate it. To this day, he may unsnap his chin strap at half time, but other then that it stays on.
This one isn't mine to deal with (I have enough of my own) but I can say that a coach, parent or fan that says they have take the word of a teenager despite what they know and see, is in for a long road. ???
